Given numbers are 415, 831, 420, 311

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 831 are 3 x 277

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

Prime factors of 311 are 311

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

Given numbers are 415, 831, 420, 311

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

Apply this formula for all numbers.

Step1:

LCM(415, 831) = 344865

GCD(415, 831) = ( 415 x 831 ) / 344865

= 415 / 831

= 415

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 415, 831, 420, 311 is 1
