Given numbers are 314, 320, 403, 639

The list of prime factors of all numbers are

Prime factors of 314 are 2 x 157

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 403 are 13 x 31

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 314, 320, 403, 639

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

Apply this formula for all numbers.

Step1:

LCM(314, 320) = 50240

GCD(314, 320) = ( 314 x 320 ) / 50240

= 314 / 320

= 314

Step2:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 314, 320, 403, 639 is 1
