Given numbers are 637, 558, 431, 763

The list of prime factors of all numbers are

Prime factors of 637 are 7 x 7 x 13

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 431 are 431

Prime factors of 763 are 7 x 109

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

Given numbers are 637, 558, 431, 763

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

Apply this formula for all numbers.

Step1:

LCM(637, 558) = 355446

GCD(637, 558) = ( 637 x 558 ) / 355446

= 637 / 558

= 637

Step2:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

Step3:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

So, Greatest Common Divisor of 637, 558, 431, 763 is 1
