Given numbers are 828, 646, 276, 821

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 646 are 2 x 17 x 19

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 821 are 821

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

Given numbers are 828, 646, 276, 821

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

Apply this formula for all numbers.

Step1:

LCM(828, 646) = 267444

GCD(828, 646) = ( 828 x 646 ) / 267444

= 828 / 646

= 828

Step2:

LCM(2, 276) = 276

GCD(2, 276) = ( 2 x 276 ) / 276

= 2 / 276

= 2

Step3:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

So, Greatest Common Divisor of 828, 646, 276, 821 is 1
