Given numbers are 772, 306, 620, 855

The list of prime factors of all numbers are

Prime factors of 772 are 2 x 2 x 193

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 772, 306, 620, 855

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

Apply this formula for all numbers.

Step1:

LCM(772, 306) = 118116

GCD(772, 306) = ( 772 x 306 ) / 118116

= 772 / 306

= 772

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 855) = 1710

GCD(2, 855) = ( 2 x 855 ) / 1710

= 2 / 855

= 2

So, Greatest Common Divisor of 772, 306, 620, 855 is 1
