Given numbers are 665, 296, 728, 725

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 296 are 2 x 2 x 2 x 37

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

Prime factors of 725 are 5 x 5 x 29

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

Given numbers are 665, 296, 728, 725

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

Apply this formula for all numbers.

Step1:

LCM(665, 296) = 196840

GCD(665, 296) = ( 665 x 296 ) / 196840

= 665 / 296

= 665

Step2:

LCM(1, 728) = 728

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

= 1 / 728

= 1

Step3:

LCM(1, 725) = 725

GCD(1, 725) = ( 1 x 725 ) / 725

= 1 / 725

= 1

So, Greatest Common Divisor of 665, 296, 728, 725 is 1
