Given numbers are 642, 877, 620, 630

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 877 are 877

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Given numbers are 642, 877, 620, 630

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

Apply this formula for all numbers.

Step1:

LCM(642, 877) = 563034

GCD(642, 877) = ( 642 x 877 ) / 563034

= 642 / 877

= 642

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 642, 877, 620, 630 is 1
