Given numbers are 728, 436, 721, 175

The list of prime factors of all numbers are

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

Prime factors of 436 are 2 x 2 x 109

Prime factors of 721 are 7 x 103

Prime factors of 175 are 5 x 5 x 7

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

Given numbers are 728, 436, 721, 175

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

Apply this formula for all numbers.

Step1:

LCM(728, 436) = 79352

GCD(728, 436) = ( 728 x 436 ) / 79352

= 728 / 436

= 728

Step2:

LCM(4, 721) = 2884

GCD(4, 721) = ( 4 x 721 ) / 2884

= 4 / 721

= 4

Step3:

LCM(1, 175) = 175

GCD(1, 175) = ( 1 x 175 ) / 175

= 1 / 175

= 1

So, Greatest Common Divisor of 728, 436, 721, 175 is 1
