Given numbers are 831, 390, 210, 919

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 919 are 919

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

Given numbers are 831, 390, 210, 919

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

Apply this formula for all numbers.

Step1:

LCM(831, 390) = 108030

GCD(831, 390) = ( 831 x 390 ) / 108030

= 831 / 390

= 831

Step2:

LCM(3, 210) = 210

GCD(3, 210) = ( 3 x 210 ) / 210

= 3 / 210

= 3

Step3:

LCM(3, 919) = 2757

GCD(3, 919) = ( 3 x 919 ) / 2757

= 3 / 919

= 3

So, Greatest Common Divisor of 831, 390, 210, 919 is 1
