Given numbers are 779, 517, 711, 840

The list of prime factors of all numbers are

Prime factors of 779 are 19 x 41

Prime factors of 517 are 11 x 47

Prime factors of 711 are 3 x 3 x 79

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

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

Given numbers are 779, 517, 711, 840

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

Apply this formula for all numbers.

Step1:

LCM(779, 517) = 402743

GCD(779, 517) = ( 779 x 517 ) / 402743

= 779 / 517

= 779

Step2:

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

= 1 / 711

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 779, 517, 711, 840 is 1
