Given numbers are 665, 728, 450, 940

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 665, 728, 450, 940

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

Apply this formula for all numbers.

Step1:

LCM(665, 728) = 69160

GCD(665, 728) = ( 665 x 728 ) / 69160

= 665 / 728

= 665

Step2:

LCM(7, 450) = 3150

GCD(7, 450) = ( 7 x 450 ) / 3150

= 7 / 450

= 7

Step3:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

So, Greatest Common Divisor of 665, 728, 450, 940 is 1
