Given numbers are 615, 314, 840, 779

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 314 are 2 x 157

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 779 are 19 x 41

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

Given numbers are 615, 314, 840, 779

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

Apply this formula for all numbers.

Step1:

LCM(615, 314) = 193110

GCD(615, 314) = ( 615 x 314 ) / 193110

= 615 / 314

= 615

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

So, Greatest Common Divisor of 615, 314, 840, 779 is 1
