Given numbers are 638, 987, 453, 624

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 987 are 3 x 7 x 47

Prime factors of 453 are 3 x 151

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 638, 987, 453, 624

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

Apply this formula for all numbers.

Step1:

LCM(638, 987) = 629706

GCD(638, 987) = ( 638 x 987 ) / 629706

= 638 / 987

= 638

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 638, 987, 453, 624 is 1
