Given numbers are 646, 630, 877, 103

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

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

Prime factors of 877 are 877

Prime factors of 103 are 103

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

Given numbers are 646, 630, 877, 103

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

Apply this formula for all numbers.

Step1:

LCM(646, 630) = 203490

GCD(646, 630) = ( 646 x 630 ) / 203490

= 646 / 630

= 646

Step2:

LCM(2, 877) = 1754

GCD(2, 877) = ( 2 x 877 ) / 1754

= 2 / 877

= 2

Step3:

LCM(1, 103) = 103

GCD(1, 103) = ( 1 x 103 ) / 103

= 1 / 103

= 1

So, Greatest Common Divisor of 646, 630, 877, 103 is 1
