Given numbers are 518, 894, 644, 861

The list of prime factors of all numbers are

Prime factors of 518 are 2 x 7 x 37

Prime factors of 894 are 2 x 3 x 149

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 518, 894, 644, 861

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

Apply this formula for all numbers.

Step1:

LCM(518, 894) = 231546

GCD(518, 894) = ( 518 x 894 ) / 231546

= 518 / 894

= 518

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

So, Greatest Common Divisor of 518, 894, 644, 861 is 1
