Given numbers are 722, 520, 128, 743

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

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

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 743 are 743

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

Given numbers are 722, 520, 128, 743

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

Apply this formula for all numbers.

Step1:

LCM(722, 520) = 187720

GCD(722, 520) = ( 722 x 520 ) / 187720

= 722 / 520

= 722

Step2:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

Step3:

LCM(2, 743) = 1486

GCD(2, 743) = ( 2 x 743 ) / 1486

= 2 / 743

= 2

So, Greatest Common Divisor of 722, 520, 128, 743 is 1
