Therefore, GCD of numbers 155, 932, 20 is 1

Given Input Data is 155, 932, 20

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

Prime Factorization of 155 is 5 x 31

Prime Factorization of 932 is 2 x 2 x 233

Prime Factorization of 20 is 2 x 2 x 5

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(155, 932) = 144460

GCD(155, 932) = ( 155 x 932 ) / 144460

GCD(155, 932) = 144460 / 144460

GCD(155, 932) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

GCD of 155, 932, 20 is 1
