Given numbers are 662, 336, 838, 639

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 838 are 2 x 419

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 662, 336, 838, 639

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

Apply this formula for all numbers.

Step1:

LCM(662, 336) = 111216

GCD(662, 336) = ( 662 x 336 ) / 111216

= 662 / 336

= 662

Step2:

LCM(2, 838) = 838

GCD(2, 838) = ( 2 x 838 ) / 838

= 2 / 838

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 662, 336, 838, 639 is 1
