Given numbers are 778, 619, 318, 780

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 619 are 619

Prime factors of 318 are 2 x 3 x 53

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

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

Given numbers are 778, 619, 318, 780

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

Apply this formula for all numbers.

Step1:

LCM(778, 619) = 481582

GCD(778, 619) = ( 778 x 619 ) / 481582

= 778 / 619

= 778

Step2:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 778, 619, 318, 780 is 1
