Given numbers are 778, 830, 972, 555

The list of prime factors of all numbers are

Prime factors of 778 are 2 x 389

Prime factors of 830 are 2 x 5 x 83

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 778, 830, 972, 555

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

Apply this formula for all numbers.

Step1:

LCM(778, 830) = 322870

GCD(778, 830) = ( 778 x 830 ) / 322870

= 778 / 830

= 778

Step2:

LCM(2, 972) = 972

GCD(2, 972) = ( 2 x 972 ) / 972

= 2 / 972

= 2

Step3:

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

= 2 / 555

= 2

So, Greatest Common Divisor of 778, 830, 972, 555 is 1
