Given Input Data is 658, 357, 525, 290

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

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 357 is 3 x 7 x 17

Prime Factorization of 525 is 3 x 5 x 5 x 7

Prime Factorization of 290 is 2 x 5 x 29

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(658, 357) = 33558

GCD(658, 357) = ( 658 x 357 ) / 33558

GCD(658, 357) = 234906 / 33558

GCD(658, 357) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 525

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

LCM(7, 525) = 525

GCD(7, 525) = ( 7 x 525 ) / 525

GCD(7, 525) = 3675 / 525

GCD(7, 525) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 290

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

LCM(7, 290) = 2030

GCD(7, 290) = ( 7 x 290 ) / 2030

GCD(7, 290) = 2030 / 2030

GCD(7, 290) = 1

GCD of 658, 357, 525, 290 is 1
