Given numbers are 561, 264, 868, 115

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 115 are 5 x 23

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

Given numbers are 561, 264, 868, 115

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

Apply this formula for all numbers.

Step1:

LCM(561, 264) = 4488

GCD(561, 264) = ( 561 x 264 ) / 4488

= 561 / 264

= 561

Step2:

LCM(33, 868) = 28644

GCD(33, 868) = ( 33 x 868 ) / 28644

= 33 / 868

= 33

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 561, 264, 868, 115 is 1
