Given numbers are 450, 875, 640, 697

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 875 are 5 x 5 x 5 x 7

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 697 are 17 x 41

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

Given numbers are 450, 875, 640, 697

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

Apply this formula for all numbers.

Step1:

LCM(450, 875) = 15750

GCD(450, 875) = ( 450 x 875 ) / 15750

= 450 / 875

= 450

Step2:

LCM(25, 640) = 3200

GCD(25, 640) = ( 25 x 640 ) / 3200

= 25 / 640

= 25

Step3:

LCM(5, 697) = 3485

GCD(5, 697) = ( 5 x 697 ) / 3485

= 5 / 697

= 5

So, Greatest Common Divisor of 450, 875, 640, 697 is 1
