Given numbers are 306, 560, 561, 211

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 561 are 3 x 11 x 17

Prime factors of 211 are 211

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

Given numbers are 306, 560, 561, 211

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

Apply this formula for all numbers.

Step1:

LCM(306, 560) = 85680

GCD(306, 560) = ( 306 x 560 ) / 85680

= 306 / 560

= 306

Step2:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 306, 560, 561, 211 is 1
