Find the greatest common factor from the list of factors for 99 and 165, and read off the answer!

Example: Find gcf of 99 and 165

Factors for 99: 1, 3, 9, 11, 33, 99
Factors for 165: 1, 3, 5, 11, 15, 33, 55, 165

Hence, GCf of 99 and 165 is 33

How do you explain GCF in mathematics?

GCF or greatest common factor of two or more numbers is defined as largest possible number or integer which is the factor of all given number or in other words we can say that largest possible common number which completely divides the given numbers. GCF of two numbers can be represented as GCF (99, 165).

Properties of GCF

The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.
GCF of two consecutive numbers is always 1.
Given two numbers 99 and 165, such that GCF is 33 where 33 will always be less than 99 and 165.
Product of two numbers is always equal to the product of their GCF and LCM.

How can we define factors?

In mathematics, a factor is a number which divides into another number exactly, without leaving any remainder. A factor of a number can be positive of negative.

Properties of Factors

Every number is a factor of zero (0), since 99 x 0 = 0 and 165 x 0 = 0.
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, 3, 9, 11, 33, 99 are exact divisors of 99 and 1, 3, 5, 11, 15, 33, 55, 165 are exact divisors of 165.
Factors of 99 are 1, 3, 9, 11, 33, 99. Each factor divides 99 without leaving a remainder.
Simlarly, factors of 165 are 1, 3, 5, 11, 15, 33, 55, 165. Each factor divides 165 without leaving a remainder.

Steps to find Factors of 99 and 165

Step 1. Find all the numbers that would divide 99 and 165 without leaving any remainder. Starting with the number 1 upto 49 (half of 99) and 1 upto 82 (half of 165). The number 1 and the number itself are always factors of the given number.

99 ÷ 1 : Remainder = 0

165 ÷ 1 : Remainder = 0

99 ÷ 3 : Remainder = 0

165 ÷ 3 : Remainder = 0

99 ÷ 9 : Remainder = 0

165 ÷ 5 : Remainder = 0

99 ÷ 11 : Remainder = 0

165 ÷ 11 : Remainder = 0

99 ÷ 33 : Remainder = 0

165 ÷ 15 : Remainder = 0

99 ÷ 99 : Remainder = 0

165 ÷ 33 : Remainder = 0

165 ÷ 55 : Remainder = 0

165 ÷ 165 : Remainder = 0

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

And, Factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165

Examples of GCF

Sammy baked 99 chocolate cookies and 165 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 99 and 165.
GCF of 99 and 165 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.

What is the relation between LCM and GCF (Greatest Common Factor)?

GCF and LCM of two numbers can be related as GCF(99, 165) = ( 99 * 165 ) / LCM(99, 165) = 33.

What is the GCF of 99 and 165?

GCF of 99 and 165 is 33.

Ram has 99 cans of Pepsi and 165 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 99 and 165. Hence GCF of 99 and 165 is 33. So the number of tables that can be arranged is 33.

Rubel is creating individual servings of starters for her birthday party. He has 99 pizzas and 165 hamburgers. He wants each serving to be identical, with no left overs. Can you help Rubel in arranging the same in greatest possible way?

The greatest number of servings Rubel can create would be equal to the GCF of 99 and 165. Thus GCF of 99 and 165 is 33.

Ariel is making ready to eat meals to share with friends. She has 99 bottles of water and 165 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 99 and 165. So the GCF of 99 and 165 is 33.

Mary has 99 blue buttons and 165 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 99 and 165. Hence, the GCF of 99 and 165 or the greatest arrangement is 33.

Kamal is making identical balloon arrangements for a party. He has 99 maroon balloons, and 165 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 99 and 165. So the GCF of 99 and 165 is 33.
