Given numbers are 315, 572, 688, 393

The list of prime factors of all numbers are

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 393 are 3 x 131

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

Given numbers are 315, 572, 688, 393

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

Apply this formula for all numbers.

Step1:

LCM(315, 572) = 180180

GCD(315, 572) = ( 315 x 572 ) / 180180

= 315 / 572

= 315

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 315, 572, 688, 393 is 1
