Given numbers are 831, 821, 248, 459

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 821 are 821

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 459 are 3 x 3 x 3 x 17

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

Given numbers are 831, 821, 248, 459

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

Apply this formula for all numbers.

Step1:

LCM(831, 821) = 682251

GCD(831, 821) = ( 831 x 821 ) / 682251

= 831 / 821

= 831

Step2:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

Step3:

LCM(1, 459) = 459

GCD(1, 459) = ( 1 x 459 ) / 459

= 1 / 459

= 1

So, Greatest Common Divisor of 831, 821, 248, 459 is 1
