What is GCF of 66 and 99?


Steps to find GCF of 66 and 99

Example: Find gcf of 66 and 99

  • Factors for 66: 1, 2, 3, 6, 11, 22, 33, 66

What is GCF of two numbers?

In mathematics GCF or also known as greatest common factor of two or more number is that one largest number which is a factor of those given numbers. It is represented as GCF (66, 99).

Properties of GCF

  • Given two numbers 66 and 99, such that GCF is 33 where 33 will always be less than 66 and 99.
  • GCF of two numbers is always equal to 1 in case given numbers are consecutive.
  • The product of GCF and LCM of two given numbers is equal to the product of two numbers.
  • The GCF of two given numbers is either 1 or the number itself if one of them is a prime number.

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 66 and 99 are factors of themselves respectively.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 3, 6, 11, 22, 33, 66 are exact divisors of 66 and 1, 3, 9, 11, 33, 99 are exact divisors of 99.
  • 1 is a factor of every number. Eg. 1 is a factor of 66 and also of 99.
  • Every number is a factor of zero (0), since 66 x 0 = 0 and 99 x 0 = 0.

Steps to find Factors of 66 and 99

  • Step 1. Find all the numbers that would divide 66 and 99 without leaving any remainder. Starting with the number 1 upto 33 (half of 66) and 1 upto 49 (half of 99). The number 1 and the number itself are always factors of the given number.
    66 ÷ 1 : Remainder = 0
    99 ÷ 1 : Remainder = 0
    66 ÷ 2 : Remainder = 0
    99 ÷ 3 : Remainder = 0
    66 ÷ 3 : Remainder = 0
    99 ÷ 9 : Remainder = 0
    66 ÷ 6 : Remainder = 0
    99 ÷ 11 : Remainder = 0
    66 ÷ 11 : Remainder = 0
    99 ÷ 33 : Remainder = 0
    66 ÷ 22 : Remainder = 0
    99 ÷ 99 : Remainder = 0
    66 ÷ 33 : Remainder = 0
    66 ÷ 66 : Remainder = 0

Hence, Factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66

And, Factors of 99 are 1, 3, 9, 11, 33, and 99

Examples of GCF

Sammy baked 66 chocolate cookies and 99 fruit and nut cookies to package in plastic containers for her friends at college. She wants to divide the cookies into identical boxes so that each box has the same number of each kind of cookies. She wishes that each box should have greatest number of cookies possible, how many plastic boxes does she need?

Since Sammy wants to pack greatest number of cookies possible. So for calculating total number of boxes required we need to calculate the GCF of 66 and 99.
GCF of 66 and 99 is 33.

A class has 66 boys and 99 girls. A choir teacher wants to form a choir team from this class such that the students are standing in equal rows also girls or boys will be in each row. Teacher wants to know the greatest number of students that could be in each row, can you help him?

To find the greatest number of students that could be in each row, we need to find the GCF of 66 and 99. Hence, GCF of 66 and 99 is 33.

What is the difference between GCF and LCM?

Major and simple difference betwen GCF and LCM is that GCF gives you the greatest common factor while LCM finds out the least common factor possible for the given numbers.

Ram has 66 cans of Pepsi and 99 cans of Coca Cola. He wants to create identical refreshment tables that will be organized in his house warming party. He also doesn't want to have any can left over. What is the greatest number of tables that Ram can arrange?

To find the greatest number of tables that Ram can stock we need to find the GCF of 66 and 99. Hence GCF of 66 and 99 is 33. So the number of tables that can be arranged is 33.

Ariel is making ready to eat meals to share with friends. She has 66 bottles of water and 99 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?

The greatest number of boxes Ariel can make would be equal to GCF of 66 and 99. So the GCF of 66 and 99 is 33.

Mary has 66 blue buttons and 99 white buttons. She wants to place them in identical groups without any buttons left, in the greatest way possible. Can you help Mary arranging them in groups?

Greatest possible way in which Mary can arrange them in groups would be GCF of 66 and 99. Hence, the GCF of 66 and 99 or the greatest arrangement is 33.

Kamal is making identical balloon arrangements for a party. He has 66 maroon balloons, and 99 orange balloons. He wants each arrangement tohave the same number of each color. What is the greatest number of arrangements that he can make if every balloon is used?

The greatest number of arrangements that he can make if every balloon is used would be equal to GCF of 66 and 99. So the GCF of 66 and 99 is 33.

Kunal is making baskets full of nuts and dried fruits. He has 66 bags of nuts and 99 bags of dried fruits. He wants each basket to be identical, containing the same combination of bags of nuts and bags of driesn fruits, with no left overs. What is the greatest number of baskets that Kunal can make?

the greatest number of baskets that Kunal can make would be equal to GCF of 66 and 99. So the GCF of 66 and 99 is 33.
