Given numbers are 642, 516, 309, 710

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 309 are 3 x 103

Prime factors of 710 are 2 x 5 x 71

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

Given numbers are 642, 516, 309, 710

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

Apply this formula for all numbers.

Step1:

LCM(642, 516) = 55212

GCD(642, 516) = ( 642 x 516 ) / 55212

= 642 / 516

= 642

Step2:

LCM(6, 309) = 618

GCD(6, 309) = ( 6 x 309 ) / 618

= 6 / 309

= 6

Step3:

LCM(3, 710) = 2130

GCD(3, 710) = ( 3 x 710 ) / 2130

= 3 / 710

= 3

So, Greatest Common Divisor of 642, 516, 309, 710 is 1
