Given numbers are 457, 720, 930, 665

The list of prime factors of all numbers are

Prime factors of 457 are 457

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

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 457, 720, 930, 665

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

Apply this formula for all numbers.

Step1:

LCM(457, 720) = 329040

GCD(457, 720) = ( 457 x 720 ) / 329040

= 457 / 720

= 457

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 457, 720, 930, 665 is 1
