Given numbers are 642, 175, 84, 702

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 175 are 5 x 5 x 7

Prime factors of 84 are 2 x 2 x 3 x 7

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

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

Given numbers are 642, 175, 84, 702

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

Apply this formula for all numbers.

Step1:

LCM(642, 175) = 112350

GCD(642, 175) = ( 642 x 175 ) / 112350

= 642 / 175

= 642

Step2:

LCM(1, 84) = 84

GCD(1, 84) = ( 1 x 84 ) / 84

= 1 / 84

= 1

Step3:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

So, Greatest Common Divisor of 642, 175, 84, 702 is 1
