Definition of GCF

Greatest common factor commonly known as GCF of the two numbers is the highest possible number which completely divides given numbers, i.e. without leaving any remainder. It is represented as GCF (70, 110).

Properties of GCF

Given two numbers 70 and 110, such that GCF is 10 where 10 will always be less than 70 and 110.
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.

What are factors?

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

Properties of Factors

Each number is a factor of itself. Eg. 70 and 110 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, 5, 7, 10, 14, 35, 70 are exact divisors of 70 and 1, 2, 5, 10, 11, 22, 55, 110 are exact divisors of 110.
1 is a factor of every number. Eg. 1 is a factor of 70 and also of 110.
Every number is a factor of zero (0), since 70 x 0 = 0 and 110 x 0 = 0.

Steps to find Factors of 70 and 110

Step 1. Find all the numbers that would divide 70 and 110 without leaving any remainder. Starting with the number 1 upto 35 (half of 70) and 1 upto 55 (half of 110). The number 1 and the number itself are always factors of the given number.

70 ÷ 1 : Remainder = 0

110 ÷ 1 : Remainder = 0

70 ÷ 2 : Remainder = 0

110 ÷ 2 : Remainder = 0

70 ÷ 5 : Remainder = 0

110 ÷ 5 : Remainder = 0

70 ÷ 7 : Remainder = 0

110 ÷ 10 : Remainder = 0

70 ÷ 10 : Remainder = 0

110 ÷ 11 : Remainder = 0

70 ÷ 14 : Remainder = 0

110 ÷ 22 : Remainder = 0

70 ÷ 35 : Remainder = 0

110 ÷ 55 : Remainder = 0

70 ÷ 70 : Remainder = 0

110 ÷ 110 : Remainder = 0

Hence, Factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70

And, Factors of 110 are 1, 2, 5, 10, 11, 22, 55, and 110

Examples of GCF

Sammy baked 70 chocolate cookies and 110 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 70 and 110.
GCF of 70 and 110 is 10.

A class has 70 boys and 110 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 70 and 110. Hence, GCF of 70 and 110 is 10.

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(70, 110) = ( 70 * 110 ) / LCM(70, 110) = 10.

What is the GCF of 70 and 110?

GCF of 70 and 110 is 10.

Ariel is making ready to eat meals to share with friends. She has 70 bottles of water and 110 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 70 and 110. So the GCF of 70 and 110 is 10.

Mary has 70 blue buttons and 110 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 70 and 110. Hence, the GCF of 70 and 110 or the greatest arrangement is 10.

Kamal is making identical balloon arrangements for a party. He has 70 maroon balloons, and 110 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 70 and 110. So the GCF of 70 and 110 is 10.

Kunal is making baskets full of nuts and dried fruits. He has 70 bags of nuts and 110 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 70 and 110. So the GCF of 70 and 110 is 10.
