### Example: Find gcf of 36 and 48

• Factors for 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
• Factors for 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

#### 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 (36, 48).

#### Properties of GCF

• The GCF of two or more given numbers cannot be greater than any of the given number. Eg- GCF of 36 and 48 is 12, where 12 is less than both 36 and 48.
• 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. 36 and 48 are factors of themselves respectively.
• 1 is a factor of every number. Eg. 1 is a factor of 36 and also of 48.
• Every number is a factor of zero (0), since 36 x 0 = 0 and 48 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, 9, 12, 18, 36 are exact divisors of 36 and 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 are exact divisors of 48.
• Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. Each factor divides 36 without leaving a remainder.
Simlarly, factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 48. Each factor divides 48 without leaving a remainder.
• Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 9, 12, 18, 36 are all less than or equal to 36 and 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 are all less than or equal to 48.

#### Steps to find Factors of 36 and 48

• Step 1. Find all the numbers that would divide 36 and 48 without leaving any remainder. Starting with the number 1 upto 18 (half of 36) and 1 upto 24 (half of 48). The number 1 and the number itself are always factors of the given number.
36 ÷ 1 : Remainder = 0
48 ÷ 1 : Remainder = 0
36 ÷ 2 : Remainder = 0
48 ÷ 2 : Remainder = 0
36 ÷ 3 : Remainder = 0
48 ÷ 3 : Remainder = 0
36 ÷ 4 : Remainder = 0
48 ÷ 4 : Remainder = 0
36 ÷ 6 : Remainder = 0
48 ÷ 6 : Remainder = 0
36 ÷ 9 : Remainder = 0
48 ÷ 8 : Remainder = 0
36 ÷ 12 : Remainder = 0
48 ÷ 12 : Remainder = 0
36 ÷ 18 : Remainder = 0
48 ÷ 16 : Remainder = 0
36 ÷ 36 : Remainder = 0
48 ÷ 24 : Remainder = 0
48 ÷ 48 : Remainder = 0

Hence, Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36

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

#### Examples of GCF

Sammy baked 36 chocolate cookies and 48 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 36 and 48.
GCF of 36 and 48 is 12.

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(36, 48) = ( 36 * 48 ) / LCM(36, 48) = 12.

What is the GCF of 36 and 48?

GCF of 36 and 48 is 12.

Ram has 36 cans of Pepsi and 48 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 36 and 48. Hence GCF of 36 and 48 is 12. So the number of tables that can be arranged is 12.
