Given numbers are 778, 779, 180, 447

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 779 are 19 x 41

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 447 are 3 x 149

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

Given numbers are 778, 779, 180, 447

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

Apply this formula for all numbers.

Step1:

LCM(778, 779) = 606062

GCD(778, 779) = ( 778 x 779 ) / 606062

= 778 / 779

= 778

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 778, 779, 180, 447 is 1
