Given numbers are 990, 555, 457, 211

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 555 are 3 x 5 x 37

Prime factors of 457 are 457

Prime factors of 211 are 211

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

Given numbers are 990, 555, 457, 211

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

Apply this formula for all numbers.

Step1:

LCM(990, 555) = 36630

GCD(990, 555) = ( 990 x 555 ) / 36630

= 990 / 555

= 990

Step2:

LCM(15, 457) = 6855

GCD(15, 457) = ( 15 x 457 ) / 6855

= 15 / 457

= 15

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 990, 555, 457, 211 is 1
