Given numbers are 831, 354, 390, 388

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 354 are 2 x 3 x 59

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

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 831, 354, 390, 388

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

Apply this formula for all numbers.

Step1:

LCM(831, 354) = 98058

GCD(831, 354) = ( 831 x 354 ) / 98058

= 831 / 354

= 831

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 388) = 1164

GCD(3, 388) = ( 3 x 388 ) / 1164

= 3 / 388

= 3

So, Greatest Common Divisor of 831, 354, 390, 388 is 1
