Given numbers are 722, 644, 558, 915

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 722, 644, 558, 915

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

Apply this formula for all numbers.

Step1:

LCM(722, 644) = 232484

GCD(722, 644) = ( 722 x 644 ) / 232484

= 722 / 644

= 722

Step2:

LCM(2, 558) = 558

GCD(2, 558) = ( 2 x 558 ) / 558

= 2 / 558

= 2

Step3:

LCM(2, 915) = 1830

GCD(2, 915) = ( 2 x 915 ) / 1830

= 2 / 915

= 2

So, Greatest Common Divisor of 722, 644, 558, 915 is 1
