Given numbers are 990, 622, 409, 671

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 622 are 2 x 311

Prime factors of 409 are 409

Prime factors of 671 are 11 x 61

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

Given numbers are 990, 622, 409, 671

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

Apply this formula for all numbers.

Step1:

LCM(990, 622) = 307890

GCD(990, 622) = ( 990 x 622 ) / 307890

= 990 / 622

= 990

Step2:

LCM(2, 409) = 818

GCD(2, 409) = ( 2 x 409 ) / 818

= 2 / 409

= 2

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 990, 622, 409, 671 is 1
