Given numbers are 427, 480, 788, 778

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 788 are 2 x 2 x 197

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 427, 480, 788, 778

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

Apply this formula for all numbers.

Step1:

LCM(427, 480) = 204960

GCD(427, 480) = ( 427 x 480 ) / 204960

= 427 / 480

= 427

Step2:

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

= 1 / 788

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 427, 480, 788, 778 is 1
