Given numbers are 638, 364, 407, 929

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 364 are 2 x 2 x 7 x 13

Prime factors of 407 are 11 x 37

Prime factors of 929 are 929

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

Given numbers are 638, 364, 407, 929

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

Apply this formula for all numbers.

Step1:

LCM(638, 364) = 116116

GCD(638, 364) = ( 638 x 364 ) / 116116

= 638 / 364

= 638

Step2:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

Step3:

LCM(1, 929) = 929

GCD(1, 929) = ( 1 x 929 ) / 929

= 1 / 929

= 1

So, Greatest Common Divisor of 638, 364, 407, 929 is 1
