Given numbers are 813, 632, 450, 405

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 632 are 2 x 2 x 2 x 79

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

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 813, 632, 450, 405

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

Apply this formula for all numbers.

Step1:

LCM(813, 632) = 513816

GCD(813, 632) = ( 813 x 632 ) / 513816

= 813 / 632

= 813

Step2:

LCM(1, 450) = 450

GCD(1, 450) = ( 1 x 450 ) / 450

= 1 / 450

= 1

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 813, 632, 450, 405 is 1
