Given numbers are 451, 456, 637, 809

The list of prime factors of all numbers are

Prime factors of 451 are 11 x 41

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 637 are 7 x 7 x 13

Prime factors of 809 are 809

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

Given numbers are 451, 456, 637, 809

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

Apply this formula for all numbers.

Step1:

LCM(451, 456) = 205656

GCD(451, 456) = ( 451 x 456 ) / 205656

= 451 / 456

= 451

Step2:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 451, 456, 637, 809 is 1
