Given numbers are 399, 418, 115, 828

The list of prime factors of all numbers are

Prime factors of 399 are 3 x 7 x 19

Prime factors of 418 are 2 x 11 x 19

Prime factors of 115 are 5 x 23

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

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

Given numbers are 399, 418, 115, 828

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

Apply this formula for all numbers.

Step1:

LCM(399, 418) = 8778

GCD(399, 418) = ( 399 x 418 ) / 8778

= 399 / 418

= 399

Step2:

LCM(19, 115) = 2185

GCD(19, 115) = ( 19 x 115 ) / 2185

= 19 / 115

= 19

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 399, 418, 115, 828 is 1
