Given numbers are 453, 805, 728, 680

The list of prime factors of all numbers are

Prime factors of 453 are 3 x 151

Prime factors of 805 are 5 x 7 x 23

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

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Given numbers are 453, 805, 728, 680

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

Apply this formula for all numbers.

Step1:

LCM(453, 805) = 364665

GCD(453, 805) = ( 453 x 805 ) / 364665

= 453 / 805

= 453

Step2:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 453, 805, 728, 680 is 1
