Given numbers are 511, 420, 122, 766

The list of prime factors of all numbers are

Prime factors of 511 are 7 x 73

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

Prime factors of 122 are 2 x 61

Prime factors of 766 are 2 x 383

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

Given numbers are 511, 420, 122, 766

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

Apply this formula for all numbers.

Step1:

LCM(511, 420) = 30660

GCD(511, 420) = ( 511 x 420 ) / 30660

= 511 / 420

= 511

Step2:

LCM(7, 122) = 854

GCD(7, 122) = ( 7 x 122 ) / 854

= 7 / 122

= 7

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 511, 420, 122, 766 is 1
