Given numbers are 778, 420, 713, 472

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 713 are 23 x 31

Prime factors of 472 are 2 x 2 x 2 x 59

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

Given numbers are 778, 420, 713, 472

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

Apply this formula for all numbers.

Step1:

LCM(778, 420) = 163380

GCD(778, 420) = ( 778 x 420 ) / 163380

= 778 / 420

= 778

Step2:

LCM(2, 713) = 1426

GCD(2, 713) = ( 2 x 713 ) / 1426

= 2 / 713

= 2

Step3:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

So, Greatest Common Divisor of 778, 420, 713, 472 is 1
