Given numbers are 561, 416, 231, 930

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 231 are 3 x 7 x 11

Prime factors of 930 are 2 x 3 x 5 x 31

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

Given numbers are 561, 416, 231, 930

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

Apply this formula for all numbers.

Step1:

LCM(561, 416) = 233376

GCD(561, 416) = ( 561 x 416 ) / 233376

= 561 / 416

= 561

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 561, 416, 231, 930 is 1
