How to find GCF of two numbers

Steps to find GCF of 43 and 65

Find all the numbers that would divide 43 and 65 without leaving any remainder as explained in factors below.
Find the greatest common factor from the list of factors for 43 and 65, and read off the answer!

Example: Find gcf of 43 and 65

Factors for 43: 1, 43
Factors for 65: 1, 5, 13, 65

Hence, GCf of 43 and 65 is 1

What does GCF mean in mathematics?

Greatest Common Fcator (GCF) or also sometimes written as greates common divisor is the largest number that can evenly divide the given two numbers. GCF is represented as GCF (43, 65).

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 43 and 65, such that GCF is 1 where 1 will always be less than 43 and 65.
Product of two numbers is always equal to the product of their GCF and LCM.

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of Factors

Every number is a factor of zero (0), since 43 x 0 = 0 and 65 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, 43 are exact divisors of 43 and 1, 5, 13, 65 are exact divisors of 65.
Factors of 43 are 1, 43. Each factor divides 43 without leaving a remainder.
Simlarly, factors of 65 are 1, 5, 13, 65. Each factor divides 65 without leaving a remainder.

Steps to find Factors of 43 and 65

Step 1. Find all the numbers that would divide 43 and 65 without leaving any remainder. Starting with the number 1 upto 21 (half of 43) and 1 upto 32 (half of 65). The number 1 and the number itself are always factors of the given number.

43 ÷ 1 : Remainder = 0

65 ÷ 1 : Remainder = 0

43 ÷ 43 : Remainder = 0

65 ÷ 5 : Remainder = 0

65 ÷ 13 : Remainder = 0

65 ÷ 65 : Remainder = 0

Hence, Factors of 43 are 1 and 43

And, Factors of 65 are 1, 5, 13, and 65

Examples of GCF

Sammy baked 43 chocolate cookies and 65 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 43 and 65.
GCF of 43 and 65 is 1.

A class has 43 boys and 65 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 43 and 65. Hence, GCF of 43 and 65 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(43, 65) = ( 43 * 65 ) / LCM(43, 65) = 1.

What is the GCF of 43 and 65?

GCF of 43 and 65 is 1.

Ariel is making ready to eat meals to share with friends. She has 43 bottles of water and 65 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 43 and 65. So the GCF of 43 and 65 is 1.

Mary has 43 blue buttons and 65 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 43 and 65. Hence, the GCF of 43 and 65 or the greatest arrangement is 1.

Kamal is making identical balloon arrangements for a party. He has 43 maroon balloons, and 65 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 43 and 65. So the GCF of 43 and 65 is 1.

Kunal is making baskets full of nuts and dried fruits. He has 43 bags of nuts and 65 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 43 and 65. So the GCF of 43 and 65 is 1.
