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 (26, 77).

Properties of GCF

Given two numbers 26 and 77, such that GCF is 1 where 1 will always be less than 26 and 77.
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. 26 and 77 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, 13, 26 are exact divisors of 26 and 1, 7, 11, 77 are exact divisors of 77.
1 is a factor of every number. Eg. 1 is a factor of 26 and also of 77.
Every number is a factor of zero (0), since 26 x 0 = 0 and 77 x 0 = 0.

Steps to find Factors of 26 and 77

Step 1. Find all the numbers that would divide 26 and 77 without leaving any remainder. Starting with the number 1 upto 13 (half of 26) and 1 upto 38 (half of 77). The number 1 and the number itself are always factors of the given number.

26 ÷ 1 : Remainder = 0

77 ÷ 1 : Remainder = 0

26 ÷ 2 : Remainder = 0

77 ÷ 7 : Remainder = 0

26 ÷ 13 : Remainder = 0

77 ÷ 11 : Remainder = 0

26 ÷ 26 : Remainder = 0

77 ÷ 77 : Remainder = 0

Hence, Factors of 26 are 1, 2, 13, and 26

And, Factors of 77 are 1, 7, 11, and 77

Examples of GCF

Sammy baked 26 chocolate cookies and 77 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 26 and 77.
GCF of 26 and 77 is 1.

A class has 26 boys and 77 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 26 and 77. Hence, GCF of 26 and 77 is 1.

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(26, 77) = ( 26 * 77 ) / LCM(26, 77) = 1.

What is the GCF of 26 and 77?

GCF of 26 and 77 is 1.

Ariel is making ready to eat meals to share with friends. She has 26 bottles of water and 77 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 26 and 77. So the GCF of 26 and 77 is 1.

Mary has 26 blue buttons and 77 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 26 and 77. Hence, the GCF of 26 and 77 or the greatest arrangement is 1.

Kamal is making identical balloon arrangements for a party. He has 26 maroon balloons, and 77 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 26 and 77. So the GCF of 26 and 77 is 1.

Kunal is making baskets full of nuts and dried fruits. He has 26 bags of nuts and 77 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 26 and 77. So the GCF of 26 and 77 is 1.
