Given numbers are 124, 215, 747, 637

The list of prime factors of all numbers are

Prime factors of 124 are 2 x 2 x 31

Prime factors of 215 are 5 x 43

Prime factors of 747 are 3 x 3 x 83

Prime factors of 637 are 7 x 7 x 13

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

Given numbers are 124, 215, 747, 637

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

Apply this formula for all numbers.

Step1:

LCM(124, 215) = 26660

GCD(124, 215) = ( 124 x 215 ) / 26660

= 124 / 215

= 124

Step2:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 124, 215, 747, 637 is 1
