The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 515 are 5 x 103

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 778, 656, 515, 140

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

Apply this formula for all numbers.

Step1:

LCM(778, 656) = 255184

GCD(778, 656) = ( 778 x 656 ) / 255184

= 778 / 656

= 778

Step2:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 778, 656, 515, 140 is 1
