Given numbers are 831, 225, 422, 401

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 422 are 2 x 211

Prime factors of 401 are 401

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

Given numbers are 831, 225, 422, 401

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

Apply this formula for all numbers.

Step1:

LCM(831, 225) = 62325

GCD(831, 225) = ( 831 x 225 ) / 62325

= 831 / 225

= 831

Step2:

LCM(3, 422) = 1266

GCD(3, 422) = ( 3 x 422 ) / 1266

= 3 / 422

= 3

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 831, 225, 422, 401 is 1
