Given numbers are 450, 390, 645, 806

The list of prime factors of all numbers are

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

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 806 are 2 x 13 x 31

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

Given numbers are 450, 390, 645, 806

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

Apply this formula for all numbers.

Step1:

LCM(450, 390) = 5850

GCD(450, 390) = ( 450 x 390 ) / 5850

= 450 / 390

= 450

Step2:

LCM(30, 645) = 1290

GCD(30, 645) = ( 30 x 645 ) / 1290

= 30 / 645

= 30

Step3:

LCM(15, 806) = 12090

GCD(15, 806) = ( 15 x 806 ) / 12090

= 15 / 806

= 15

So, Greatest Common Divisor of 450, 390, 645, 806 is 1
