Given numbers are 721, 715, 520, 375

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 715 are 5 x 11 x 13

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 375 are 3 x 5 x 5 x 5

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

Given numbers are 721, 715, 520, 375

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

Apply this formula for all numbers.

Step1:

LCM(721, 715) = 515515

GCD(721, 715) = ( 721 x 715 ) / 515515

= 721 / 715

= 721

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

So, Greatest Common Divisor of 721, 715, 520, 375 is 1
