Given numbers are 918, 810, 916, 643

The list of prime factors of all numbers are

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 916 are 2 x 2 x 229

Prime factors of 643 are 643

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

Given numbers are 918, 810, 916, 643

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

Apply this formula for all numbers.

Step1:

LCM(918, 810) = 13770

GCD(918, 810) = ( 918 x 810 ) / 13770

= 918 / 810

= 918

Step2:

LCM(54, 916) = 24732

GCD(54, 916) = ( 54 x 916 ) / 24732

= 54 / 916

= 54

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 918, 810, 916, 643 is 1
