Given numbers are 990, 816, 891, 151

The list of prime factors of all numbers are

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 151 are 151

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

Given numbers are 990, 816, 891, 151

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

Apply this formula for all numbers.

Step1:

LCM(990, 816) = 134640

GCD(990, 816) = ( 990 x 816 ) / 134640

= 990 / 816

= 990

Step2:

LCM(6, 891) = 1782

GCD(6, 891) = ( 6 x 891 ) / 1782

= 6 / 891

= 6

Step3:

LCM(3, 151) = 453

GCD(3, 151) = ( 3 x 151 ) / 453

= 3 / 151

= 3

So, Greatest Common Divisor of 990, 816, 891, 151 is 1
