Given numbers are 828, 399, 835, 391

The list of prime factors of all numbers are

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 399 are 3 x 7 x 19

Prime factors of 835 are 5 x 167

Prime factors of 391 are 17 x 23

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

Given numbers are 828, 399, 835, 391

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

Apply this formula for all numbers.

Step1:

LCM(828, 399) = 110124

GCD(828, 399) = ( 828 x 399 ) / 110124

= 828 / 399

= 828

Step2:

LCM(3, 835) = 2505

GCD(3, 835) = ( 3 x 835 ) / 2505

= 3 / 835

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 828, 399, 835, 391 is 1
