Given numbers are 662, 574, 780, 779

The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

Prime factors of 574 are 2 x 7 x 41

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

Prime factors of 779 are 19 x 41

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

Given numbers are 662, 574, 780, 779

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

Apply this formula for all numbers.

Step1:

LCM(662, 574) = 189994

GCD(662, 574) = ( 662 x 574 ) / 189994

= 662 / 574

= 662

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 779) = 1558

GCD(2, 779) = ( 2 x 779 ) / 1558

= 2 / 779

= 2

So, Greatest Common Divisor of 662, 574, 780, 779 is 1
