Given numbers are 813, 723, 450, 821

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 723 are 3 x 241

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 821 are 821

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

Given numbers are 813, 723, 450, 821

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

Apply this formula for all numbers.

Step1:

LCM(813, 723) = 195933

GCD(813, 723) = ( 813 x 723 ) / 195933

= 813 / 723

= 813

Step2:

LCM(3, 450) = 450

GCD(3, 450) = ( 3 x 450 ) / 450

= 3 / 450

= 3

Step3:

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

= 3 / 821

= 3

So, Greatest Common Divisor of 813, 723, 450, 821 is 1
