Given numbers are 721, 427, 930, 308

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 427 are 7 x 61

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 721, 427, 930, 308

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

Apply this formula for all numbers.

Step1:

LCM(721, 427) = 43981

GCD(721, 427) = ( 721 x 427 ) / 43981

= 721 / 427

= 721

Step2:

LCM(7, 930) = 6510

GCD(7, 930) = ( 7 x 930 ) / 6510

= 7 / 930

= 7

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 721, 427, 930, 308 is 1
