Given numbers are 678, 693, 780, 778

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 693 are 3 x 3 x 7 x 11

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

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 678, 693, 780, 778

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

Apply this formula for all numbers.

Step1:

LCM(678, 693) = 156618

GCD(678, 693) = ( 678 x 693 ) / 156618

= 678 / 693

= 678

Step2:

LCM(3, 780) = 780

GCD(3, 780) = ( 3 x 780 ) / 780

= 3 / 780

= 3

Step3:

LCM(3, 778) = 2334

GCD(3, 778) = ( 3 x 778 ) / 2334

= 3 / 778

= 3

So, Greatest Common Divisor of 678, 693, 780, 778 is 1
