Given numbers are 861, 645, 177, 566

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 645 are 3 x 5 x 43

Prime factors of 177 are 3 x 59

Prime factors of 566 are 2 x 283

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

Given numbers are 861, 645, 177, 566

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

Apply this formula for all numbers.

Step1:

LCM(861, 645) = 185115

GCD(861, 645) = ( 861 x 645 ) / 185115

= 861 / 645

= 861

Step2:

LCM(3, 177) = 177

GCD(3, 177) = ( 3 x 177 ) / 177

= 3 / 177

= 3

Step3:

LCM(3, 566) = 1698

GCD(3, 566) = ( 3 x 566 ) / 1698

= 3 / 566

= 3

So, Greatest Common Divisor of 861, 645, 177, 566 is 1
