Therefore, GCD of numbers 655, 125, 24, 615 is 1

Given Input Data is 655, 125, 24, 615

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 655 is 5 x 131

Prime Factorization of 125 is 5 x 5 x 5

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 615 is 3 x 5 x 41

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(655, 125) = 16375

GCD(655, 125) = ( 655 x 125 ) / 16375

GCD(655, 125) = 81875 / 16375

GCD(655, 125) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 24

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 24) = 120

GCD(5, 24) = ( 5 x 24 ) / 120

GCD(5, 24) = 120 / 120

GCD(5, 24) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 615

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

GCD(1, 615) = 615 / 615

GCD(1, 615) = 1

GCD of 655, 125, 24, 615 is 1
