Given numbers are 642, 211, 308, 610

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 211 are 211

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 610 are 2 x 5 x 61

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

Given numbers are 642, 211, 308, 610

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

Apply this formula for all numbers.

Step1:

LCM(642, 211) = 135462

GCD(642, 211) = ( 642 x 211 ) / 135462

= 642 / 211

= 642

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

So, Greatest Common Divisor of 642, 211, 308, 610 is 1
