Given numbers are 820, 828, 406, 303

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

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

Prime factors of 406 are 2 x 7 x 29

Prime factors of 303 are 3 x 101

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

Given numbers are 820, 828, 406, 303

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

Apply this formula for all numbers.

Step1:

LCM(820, 828) = 169740

GCD(820, 828) = ( 820 x 828 ) / 169740

= 820 / 828

= 820

Step2:

LCM(4, 406) = 812

GCD(4, 406) = ( 4 x 406 ) / 812

= 4 / 406

= 4

Step3:

LCM(2, 303) = 606

GCD(2, 303) = ( 2 x 303 ) / 606

= 2 / 303

= 2

So, Greatest Common Divisor of 820, 828, 406, 303 is 1
