Given numbers are 781, 346, 615, 321

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 346 are 2 x 173

Prime factors of 615 are 3 x 5 x 41

Prime factors of 321 are 3 x 107

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

Given numbers are 781, 346, 615, 321

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

Apply this formula for all numbers.

Step1:

LCM(781, 346) = 270226

GCD(781, 346) = ( 781 x 346 ) / 270226

= 781 / 346

= 781

Step2:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 781, 346, 615, 321 is 1
