### Example: Find gcf of 24 and 100

• Factors for 24: 1, 2, 3, 4, 6, 8, 12, 24
• Factors for 100: 1, 2, 4, 5, 10, 20, 25, 50, 100

Hence, GCf of 24 and 100 is 4

#### How do you explain GCF in mathematics?

GCF or greatest common factor of two or more numbers is defined as largest possible number or integer which is the factor of all given number or in other words we can say that largest possible common number which completely divides the given numbers. GCF of two numbers can be represented as GCF (24, 100).

#### Properties of GCF

• The GCF of two or more given numbers cannot be greater than any of the given number. Eg- GCF of 24 and 100 is 4, where 4 is less than both 24 and 100.
• 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 number exactly, without leaving any remainder. A factor of a number can be positive of negative.

#### Properties of Factors

• Each number is a factor of itself. Eg. 24 and 100 are factors of themselves respectively.
• 1 is a factor of every number. Eg. 1 is a factor of 24 and also of 100.
• Every number is a factor of zero (0), since 24 x 0 = 0 and 100 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, 24 are exact divisors of 24 and 1, 2, 4, 5, 10, 20, 25, 50, 100 are exact divisors of 100.
• Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. Each factor divides 24 without leaving a remainder.
Simlarly, factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100. Each factor divides 100 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, 24 are all less than or equal to 24 and 1, 2, 4, 5, 10, 20, 25, 50, 100 are all less than or equal to 100.

#### Steps to find Factors of 24 and 100

• Step 1. Find all the numbers that would divide 24 and 100 without leaving any remainder. Starting with the number 1 upto 12 (half of 24) and 1 upto 50 (half of 100). The number 1 and the number itself are always factors of the given number.
24 ÷ 1 : Remainder = 0
100 ÷ 1 : Remainder = 0
24 ÷ 2 : Remainder = 0
100 ÷ 2 : Remainder = 0
24 ÷ 3 : Remainder = 0
100 ÷ 4 : Remainder = 0
24 ÷ 4 : Remainder = 0
100 ÷ 5 : Remainder = 0
24 ÷ 6 : Remainder = 0
100 ÷ 10 : Remainder = 0
24 ÷ 8 : Remainder = 0
100 ÷ 20 : Remainder = 0
24 ÷ 12 : Remainder = 0
100 ÷ 25 : Remainder = 0
24 ÷ 24 : Remainder = 0
100 ÷ 50 : Remainder = 0
100 ÷ 100 : Remainder = 0

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

And, Factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100

#### Examples of GCF

What is the relation between LCM and GCF (Greatest Common Factor)?

GCF and LCM of two numbers can be related as GCF(24, 100) = ( 24 * 100 ) / LCM(24, 100) = 4.

What is the GCF of 24 and 100?

GCF of 24 and 100 is 4.
