Given numbers are 390, 635, 147, 702

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 635 are 5 x 127

Prime factors of 147 are 3 x 7 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 390, 635, 147, 702

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

Apply this formula for all numbers.

Step1:

LCM(390, 635) = 49530

GCD(390, 635) = ( 390 x 635 ) / 49530

= 390 / 635

= 390

Step2:

LCM(5, 147) = 735

GCD(5, 147) = ( 5 x 147 ) / 735

= 5 / 147

= 5

Step3:

LCM(1, 702) = 702

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

= 1 / 702

= 1

So, Greatest Common Divisor of 390, 635, 147, 702 is 1
