Given numbers are 637, 798, 455, 624

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 798 are 2 x 3 x 7 x 19

Prime factors of 455 are 5 x 7 x 13

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 637, 798, 455, 624

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

Apply this formula for all numbers.

Step1:

LCM(637, 798) = 72618

GCD(637, 798) = ( 637 x 798 ) / 72618

= 637 / 798

= 637

Step2:

LCM(7, 455) = 455

GCD(7, 455) = ( 7 x 455 ) / 455

= 7 / 455

= 7

Step3:

LCM(7, 624) = 4368

GCD(7, 624) = ( 7 x 624 ) / 4368

= 7 / 624

= 7

So, Greatest Common Divisor of 637, 798, 455, 624 is 1
