Given numbers are 638, 847, 350, 424

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 847 are 7 x 11 x 11

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 424 are 2 x 2 x 2 x 53

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

Given numbers are 638, 847, 350, 424

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

Apply this formula for all numbers.

Step1:

LCM(638, 847) = 49126

GCD(638, 847) = ( 638 x 847 ) / 49126

= 638 / 847

= 638

Step2:

LCM(11, 350) = 3850

GCD(11, 350) = ( 11 x 350 ) / 3850

= 11 / 350

= 11

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 638, 847, 350, 424 is 1
