Given numbers are 728, 312, 292, 561

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 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 292 are 2 x 2 x 73

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 728, 312, 292, 561

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

Apply this formula for all numbers.

Step1:

LCM(728, 312) = 2184

GCD(728, 312) = ( 728 x 312 ) / 2184

= 728 / 312

= 728

Step2:

LCM(104, 292) = 7592

GCD(104, 292) = ( 104 x 292 ) / 7592

= 104 / 292

= 104

Step3:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

So, Greatest Common Divisor of 728, 312, 292, 561 is 1
