#### 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 (48, 80).

#### Properties of GCF

• The GCF of two or more given numbers cannot be greater than any of the given number. Eg- GCF of 48 and 80 is 16, where 16 is less than both 48 and 80.
• 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.

#### 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

• Each number is a factor of itself. Eg. 48 and 80 are factors of themselves respectively.
• 1 is a factor of every number. Eg. 1 is a factor of 48 and also of 80.
• Every number is a factor of zero (0), since 48 x 0 = 0 and 80 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, 3, 4, 6, 8, 12, 16, 24, 48 are exact divisors of 48 and 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 are exact divisors of 80.
• Factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48. Each factor divides 48 without leaving a remainder.
Simlarly, factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80. Each factor divides 80 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 are all less than or equal to 48 and 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 are all less than or equal to 80.

#### Steps to find Factors of 48 and 80

• Step 1. Find all the numbers that would divide 48 and 80 without leaving any remainder. Starting with the number 1 upto 24 (half of 48) and 1 upto 40 (half of 80). The number 1 and the number itself are always factors of the given number.
48 ÷ 1 : Remainder = 0
80 ÷ 1 : Remainder = 0
48 ÷ 2 : Remainder = 0
80 ÷ 2 : Remainder = 0
48 ÷ 3 : Remainder = 0
80 ÷ 4 : Remainder = 0
48 ÷ 4 : Remainder = 0
80 ÷ 5 : Remainder = 0
48 ÷ 6 : Remainder = 0
80 ÷ 8 : Remainder = 0
48 ÷ 8 : Remainder = 0
80 ÷ 10 : Remainder = 0
48 ÷ 12 : Remainder = 0
80 ÷ 16 : Remainder = 0
48 ÷ 16 : Remainder = 0
80 ÷ 20 : Remainder = 0
48 ÷ 24 : Remainder = 0
80 ÷ 40 : Remainder = 0
48 ÷ 48 : Remainder = 0
80 ÷ 80 : Remainder = 0

Hence, Factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48

And, Factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80

#### Examples of GCF

Sammy baked 48 chocolate cookies and 80 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 48 and 80.
GCF of 48 and 80 is 16.

A class has 48 boys and 80 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 48 and 80. Hence, GCF of 48 and 80 is 16.

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.

Ram has 48 cans of Pepsi and 80 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 48 and 80. Hence GCF of 48 and 80 is 16. So the number of tables that can be arranged is 16.

Ariel is making ready to eat meals to share with friends. She has 48 bottles of water and 80 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 48 and 80. So the GCF of 48 and 80 is 16.
