Given numbers are 308, 780, 679, 615

The list of prime factors of all numbers are

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 679 are 7 x 97

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 308, 780, 679, 615

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

Apply this formula for all numbers.

Step1:

LCM(308, 780) = 60060

GCD(308, 780) = ( 308 x 780 ) / 60060

= 308 / 780

= 308

Step2:

LCM(4, 679) = 2716

GCD(4, 679) = ( 4 x 679 ) / 2716

= 4 / 679

= 4

Step3:

LCM(1, 615) = 615

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

= 1 / 615

= 1

So, Greatest Common Divisor of 308, 780, 679, 615 is 1
