Given numbers are 318, 138, 557, 147

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 138 are 2 x 3 x 23

Prime factors of 557 are 557

Prime factors of 147 are 3 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 318, 138, 557, 147

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(318, 138) = 7314

GCD(318, 138) = ( 318 x 138 ) / 7314

= 318 / 138

= 318

Step2:

LCM(6, 557) = 3342

GCD(6, 557) = ( 6 x 557 ) / 3342

= 6 / 557

= 6

Step3:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

So, Greatest Common Divisor of 318, 138, 557, 147 is 1
