How to find GCF of two numbers

Steps to find GCF of 47 and 63

Find all the numbers that would divide 47 and 63 without leaving any remainder as explained in factors below.
Find the greatest common factor from the list of factors for 47 and 63, and read off the answer!

Example: Find gcf of 47 and 63

Factors for 47: 1, 47
Factors for 63: 1, 3, 7, 9, 21, 63

Hence, GCf of 47 and 63 is 1

How do we define GCF?

In mathematics we use GCF or greatest common method to find out the greatest possible positive integer which can completely divide the given numbers. It is written as GCF (47, 63).

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 47 and 63, such that GCF is 1 where 1 will always be less than 47 and 63.
Product of two numbers is always equal to the product of their GCF and LCM.

How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

Properties of Factors

Every number is a factor of zero (0), since 47 x 0 = 0 and 63 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, 47 are exact divisors of 47 and 1, 3, 7, 9, 21, 63 are exact divisors of 63.
Factors of 47 are 1, 47. Each factor divides 47 without leaving a remainder.
Simlarly, factors of 63 are 1, 3, 7, 9, 21, 63. Each factor divides 63 without leaving a remainder.

Steps to find Factors of 47 and 63

Step 1. Find all the numbers that would divide 47 and 63 without leaving any remainder. Starting with the number 1 upto 23 (half of 47) and 1 upto 31 (half of 63). The number 1 and the number itself are always factors of the given number.

47 ÷ 1 : Remainder = 0

63 ÷ 1 : Remainder = 0

47 ÷ 47 : Remainder = 0

63 ÷ 3 : Remainder = 0

63 ÷ 7 : Remainder = 0

63 ÷ 9 : Remainder = 0

63 ÷ 21 : Remainder = 0

63 ÷ 63 : Remainder = 0

Hence, Factors of 47 are 1 and 47

And, Factors of 63 are 1, 3, 7, 9, 21, and 63

Examples of GCF

A class has 47 boys and 63 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 47 and 63. Hence, GCF of 47 and 63 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(47, 63) = ( 47 * 63 ) / LCM(47, 63) = 1.

What is the GCF of 47 and 63?

GCF of 47 and 63 is 1.

Ram has 47 cans of Pepsi and 63 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 47 and 63. Hence GCF of 47 and 63 is 1. So the number of tables that can be arranged is 1.

Rubel is creating individual servings of starters for her birthday party. He has 47 pizzas and 63 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 47 and 63. Thus GCF of 47 and 63 is 1.

Ariel is making ready to eat meals to share with friends. She has 47 bottles of water and 63 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 47 and 63. So the GCF of 47 and 63 is 1.

Mary has 47 blue buttons and 63 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 47 and 63. Hence, the GCF of 47 and 63 or the greatest arrangement is 1.

Kunal is making baskets full of nuts and dried fruits. He has 47 bags of nuts and 63 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 47 and 63. So the GCF of 47 and 63 is 1.
