Given numbers are 764, 646, 301, 390

The list of prime factors of all numbers are

Prime factors of 764 are 2 x 2 x 191

Prime factors of 646 are 2 x 17 x 19

Prime factors of 301 are 7 x 43

Prime factors of 390 are 2 x 3 x 5 x 13

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

Given numbers are 764, 646, 301, 390

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

Apply this formula for all numbers.

Step1:

LCM(764, 646) = 246772

GCD(764, 646) = ( 764 x 646 ) / 246772

= 764 / 646

= 764

Step2:

LCM(2, 301) = 602

GCD(2, 301) = ( 2 x 301 ) / 602

= 2 / 301

= 2

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 764, 646, 301, 390 is 1
