Given numbers are 450, 531, 720, 641

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 531 are 3 x 3 x 59

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 641 are 641

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

Given numbers are 450, 531, 720, 641

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

Apply this formula for all numbers.

Step1:

LCM(450, 531) = 26550

GCD(450, 531) = ( 450 x 531 ) / 26550

= 450 / 531

= 450

Step2:

LCM(9, 720) = 720

GCD(9, 720) = ( 9 x 720 ) / 720

= 9 / 720

= 9

Step3:

LCM(9, 641) = 5769

GCD(9, 641) = ( 9 x 641 ) / 5769

= 9 / 641

= 9

So, Greatest Common Divisor of 450, 531, 720, 641 is 1
