Given numbers are 990, 173, 456, 821

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 173 are 173

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 821 are 821

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

Given numbers are 990, 173, 456, 821

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

Apply this formula for all numbers.

Step1:

LCM(990, 173) = 171270

GCD(990, 173) = ( 990 x 173 ) / 171270

= 990 / 173

= 990

Step2:

LCM(1, 456) = 456

GCD(1, 456) = ( 1 x 456 ) / 456

= 1 / 456

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 990, 173, 456, 821 is 1
