Given numbers are 311, 480, 55, 861

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 55 are 5 x 11

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 311, 480, 55, 861

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

Apply this formula for all numbers.

Step1:

LCM(311, 480) = 149280

GCD(311, 480) = ( 311 x 480 ) / 149280

= 311 / 480

= 311

Step2:

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

= 1 / 55

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 311, 480, 55, 861 is 1
