Given numbers are 778, 748, 427, 810

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 748 are 2 x 2 x 11 x 17

Prime factors of 427 are 7 x 61

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 778, 748, 427, 810

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

Apply this formula for all numbers.

Step1:

LCM(778, 748) = 290972

GCD(778, 748) = ( 778 x 748 ) / 290972

= 778 / 748

= 778

Step2:

LCM(2, 427) = 854

GCD(2, 427) = ( 2 x 427 ) / 854

= 2 / 427

= 2

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 778, 748, 427, 810 is 1
