Given numbers are 518, 355, 861, 778

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 355 are 5 x 71

Prime factors of 861 are 3 x 7 x 41

Prime factors of 778 are 2 x 389

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

Given numbers are 518, 355, 861, 778

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

Apply this formula for all numbers.

Step1:

LCM(518, 355) = 183890

GCD(518, 355) = ( 518 x 355 ) / 183890

= 518 / 355

= 518

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 518, 355, 861, 778 is 1
