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 (16, 22).

Properties of GCF

The GCF of two or more given numbers cannot be greater than any of the given number. Eg- GCF of 16 and 22 is 2, where 2 is less than both 16 and 22.
GCF of two consecutive numbers is always 1.
The product of GCF and LCM of two given numbers is equal to the product of two numbers.
The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.

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. 16 and 22 are factors of themselves respectively.
1 is a factor of every number. Eg. 1 is a factor of 16 and also of 22.
Every number is a factor of zero (0), since 16 x 0 = 0 and 22 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, 2, 4, 8, 16 are exact divisors of 16 and 1, 2, 11, 22 are exact divisors of 22.
Factors of 16 are 1, 2, 4, 8, 16. Each factor divides 16 without leaving a remainder.
Simlarly, factors of 22 are 1, 2, 11, 22. Each factor divides 22 without leaving a remainder.
Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 8, 16 are all less than or equal to 16 and 1, 2, 11, 22 are all less than or equal to 22.

Steps to find Factors of 16 and 22

Step 1. Find all the numbers that would divide 16 and 22 without leaving any remainder. Starting with the number 1 upto 8 (half of 16) and 1 upto 11 (half of 22). The number 1 and the number itself are always factors of the given number.

16 ÷ 1 : Remainder = 0

22 ÷ 1 : Remainder = 0

16 ÷ 2 : Remainder = 0

22 ÷ 2 : Remainder = 0

16 ÷ 4 : Remainder = 0

22 ÷ 11 : Remainder = 0

16 ÷ 8 : Remainder = 0

22 ÷ 22 : Remainder = 0

16 ÷ 16 : Remainder = 0

Hence, Factors of 16 are 1, 2, 4, 8, and 16

And, Factors of 22 are 1, 2, 11, and 22

Examples of GCF

Sammy baked 16 chocolate cookies and 22 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 16 and 22.
GCF of 16 and 22 is 2.

A class has 16 boys and 22 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 16 and 22. Hence, GCF of 16 and 22 is 2.

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(16, 22) = ( 16 * 22 ) / LCM(16, 22) = 2.

What is the GCF of 16 and 22?

GCF of 16 and 22 is 2.

Ariel is making ready to eat meals to share with friends. She has 16 bottles of water and 22 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 16 and 22. So the GCF of 16 and 22 is 2.

Mary has 16 blue buttons and 22 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 16 and 22. Hence, the GCF of 16 and 22 or the greatest arrangement is 2.

Kamal is making identical balloon arrangements for a party. He has 16 maroon balloons, and 22 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 16 and 22. So the GCF of 16 and 22 is 2.

Kunal is making baskets full of nuts and dried fruits. He has 16 bags of nuts and 22 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 16 and 22. So the GCF of 16 and 22 is 2.
