Given Input Data is 855, 625, 553

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

Prime Factorization of 855 is 3 x 3 x 5 x 19

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 553 is 7 x 79

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(855, 625) = 106875

GCD(855, 625) = ( 855 x 625 ) / 106875

GCD(855, 625) = 534375 / 106875

GCD(855, 625) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 553

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

LCM(5, 553) = 2765

GCD(5, 553) = ( 5 x 553 ) / 2765

GCD(5, 553) = 2765 / 2765

GCD(5, 553) = 1

GCD of 855, 625, 553 is 1
