Given numbers are 638, 785, 650, 429

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 785 are 5 x 157

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 429 are 3 x 11 x 13

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

Given numbers are 638, 785, 650, 429

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

Apply this formula for all numbers.

Step1:

LCM(638, 785) = 500830

GCD(638, 785) = ( 638 x 785 ) / 500830

= 638 / 785

= 638

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

Step3:

LCM(1, 429) = 429

GCD(1, 429) = ( 1 x 429 ) / 429

= 1 / 429

= 1

So, Greatest Common Divisor of 638, 785, 650, 429 is 1
