Given numbers are 981, 216, 661, 966

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 661 are 661

Prime factors of 966 are 2 x 3 x 7 x 23

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

Given numbers are 981, 216, 661, 966

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

Apply this formula for all numbers.

Step1:

LCM(981, 216) = 23544

GCD(981, 216) = ( 981 x 216 ) / 23544

= 981 / 216

= 981

Step2:

LCM(9, 661) = 5949

GCD(9, 661) = ( 9 x 661 ) / 5949

= 9 / 661

= 9

Step3:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

So, Greatest Common Divisor of 981, 216, 661, 966 is 1
