Therefore, GCD of numbers 645, 125, 88, 992 is 1

Given Input Data is 645, 125, 88, 992

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 125 is 5 x 5 x 5

Prime Factorization of 88 is 2 x 2 x 2 x 11

Prime Factorization of 992 is 2 x 2 x 2 x 2 x 2 x 31

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(645, 125) = 16125

GCD(645, 125) = ( 645 x 125 ) / 16125

GCD(645, 125) = 80625 / 16125

GCD(645, 125) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 88

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

LCM(5, 88) = 440

GCD(5, 88) = ( 5 x 88 ) / 440

GCD(5, 88) = 440 / 440

GCD(5, 88) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 992

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

LCM(1, 992) = 992

GCD(1, 992) = ( 1 x 992 ) / 992

GCD(1, 992) = 992 / 992

GCD(1, 992) = 1

GCD of 645, 125, 88, 992 is 1
