Given numbers are 638, 633, 800, 450

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 633 are 3 x 211

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

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

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

Given numbers are 638, 633, 800, 450

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

Apply this formula for all numbers.

Step1:

LCM(638, 633) = 403854

GCD(638, 633) = ( 638 x 633 ) / 403854

= 638 / 633

= 638

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 450) = 450

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

= 1 / 450

= 1

So, Greatest Common Divisor of 638, 633, 800, 450 is 1
