Given numbers are 672, 217, 457, 845

The list of prime factors of all numbers are

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 217 are 7 x 31

Prime factors of 457 are 457

Prime factors of 845 are 5 x 13 x 13

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

Given numbers are 672, 217, 457, 845

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

Apply this formula for all numbers.

Step1:

LCM(672, 217) = 20832

GCD(672, 217) = ( 672 x 217 ) / 20832

= 672 / 217

= 672

Step2:

LCM(7, 457) = 3199

GCD(7, 457) = ( 7 x 457 ) / 3199

= 7 / 457

= 7

Step3:

LCM(1, 845) = 845

GCD(1, 845) = ( 1 x 845 ) / 845

= 1 / 845

= 1

So, Greatest Common Divisor of 672, 217, 457, 845 is 1
