Given numbers are 321, 688, 302, 147

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

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

Prime factors of 302 are 2 x 151

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 321, 688, 302, 147

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

Apply this formula for all numbers.

Step1:

LCM(321, 688) = 220848

GCD(321, 688) = ( 321 x 688 ) / 220848

= 321 / 688

= 321

Step2:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1

Step3:

LCM(1, 147) = 147

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

= 1 / 147

= 1

So, Greatest Common Divisor of 321, 688, 302, 147 is 1
