Given numbers are 561, 306, 852, 871

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

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

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 871 are 13 x 67

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

Given numbers are 561, 306, 852, 871

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

Apply this formula for all numbers.

Step1:

LCM(561, 306) = 3366

GCD(561, 306) = ( 561 x 306 ) / 3366

= 561 / 306

= 561

Step2:

LCM(51, 852) = 14484

GCD(51, 852) = ( 51 x 852 ) / 14484

= 51 / 852

= 51

Step3:

LCM(3, 871) = 2613

GCD(3, 871) = ( 3 x 871 ) / 2613

= 3 / 871

= 3

So, Greatest Common Divisor of 561, 306, 852, 871 is 1
