Given numbers are 642, 651, 466, 311

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 651 are 3 x 7 x 31

Prime factors of 466 are 2 x 233

Prime factors of 311 are 311

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

Given numbers are 642, 651, 466, 311

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

Apply this formula for all numbers.

Step1:

LCM(642, 651) = 139314

GCD(642, 651) = ( 642 x 651 ) / 139314

= 642 / 651

= 642

Step2:

LCM(3, 466) = 1398

GCD(3, 466) = ( 3 x 466 ) / 1398

= 3 / 466

= 3

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 642, 651, 466, 311 is 1
