Given numbers are 561, 847, 564, 945

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 847 are 7 x 11 x 11

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 561, 847, 564, 945

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

Apply this formula for all numbers.

Step1:

LCM(561, 847) = 43197

GCD(561, 847) = ( 561 x 847 ) / 43197

= 561 / 847

= 561

Step2:

LCM(11, 564) = 6204

GCD(11, 564) = ( 11 x 564 ) / 6204

= 11 / 564

= 11

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 561, 847, 564, 945 is 1
