Given numbers are 780, 309, 517, 968

The list of prime factors of all numbers are

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

Prime factors of 309 are 3 x 103

Prime factors of 517 are 11 x 47

Prime factors of 968 are 2 x 2 x 2 x 11 x 11

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

Given numbers are 780, 309, 517, 968

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

Apply this formula for all numbers.

Step1:

LCM(780, 309) = 80340

GCD(780, 309) = ( 780 x 309 ) / 80340

= 780 / 309

= 780

Step2:

LCM(3, 517) = 1551

GCD(3, 517) = ( 3 x 517 ) / 1551

= 3 / 517

= 3

Step3:

LCM(1, 968) = 968

GCD(1, 968) = ( 1 x 968 ) / 968

= 1 / 968

= 1

So, Greatest Common Divisor of 780, 309, 517, 968 is 1
