Given Input Data is 525, 837, 815, 117

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

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

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 815 is 5 x 163

Prime Factorization of 117 is 3 x 3 x 13

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(525, 837) = 146475

GCD(525, 837) = ( 525 x 837 ) / 146475

GCD(525, 837) = 439425 / 146475

GCD(525, 837) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 815

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

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

GCD(3, 815) = 2445 / 2445

GCD(3, 815) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 117

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

LCM(1, 117) = 117

GCD(1, 117) = ( 1 x 117 ) / 117

GCD(1, 117) = 117 / 117

GCD(1, 117) = 1

GCD of 525, 837, 815, 117 is 1
