Given numbers are 778, 642, 987, 510

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 642 are 2 x 3 x 107

Prime factors of 987 are 3 x 7 x 47

Prime factors of 510 are 2 x 3 x 5 x 17

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

Given numbers are 778, 642, 987, 510

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

Apply this formula for all numbers.

Step1:

LCM(778, 642) = 249738

GCD(778, 642) = ( 778 x 642 ) / 249738

= 778 / 642

= 778

Step2:

LCM(2, 987) = 1974

GCD(2, 987) = ( 2 x 987 ) / 1974

= 2 / 987

= 2

Step3:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

So, Greatest Common Divisor of 778, 642, 987, 510 is 1
