Given numbers are 981, 418, 916, 816

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 418 are 2 x 11 x 19

Prime factors of 916 are 2 x 2 x 229

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 981, 418, 916, 816

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

Apply this formula for all numbers.

Step1:

LCM(981, 418) = 410058

GCD(981, 418) = ( 981 x 418 ) / 410058

= 981 / 418

= 981

Step2:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 981, 418, 916, 816 is 1
