Given numbers are 642, 710, 772, 511

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 710 are 2 x 5 x 71

Prime factors of 772 are 2 x 2 x 193

Prime factors of 511 are 7 x 73

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

Given numbers are 642, 710, 772, 511

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

Apply this formula for all numbers.

Step1:

LCM(642, 710) = 227910

GCD(642, 710) = ( 642 x 710 ) / 227910

= 642 / 710

= 642

Step2:

LCM(2, 772) = 772

GCD(2, 772) = ( 2 x 772 ) / 772

= 2 / 772

= 2

Step3:

LCM(2, 511) = 1022

GCD(2, 511) = ( 2 x 511 ) / 1022

= 2 / 511

= 2

So, Greatest Common Divisor of 642, 710, 772, 511 is 1
