Given numbers are 634, 643, 451, 518

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 643 are 643

Prime factors of 451 are 11 x 41

Prime factors of 518 are 2 x 7 x 37

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

Given numbers are 634, 643, 451, 518

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

Apply this formula for all numbers.

Step1:

LCM(634, 643) = 407662

GCD(634, 643) = ( 634 x 643 ) / 407662

= 634 / 643

= 634

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 634, 643, 451, 518 is 1
