Given numbers are 990, 623, 30, 662

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 623 are 7 x 89

Prime factors of 30 are 2 x 3 x 5

Prime factors of 662 are 2 x 331

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

Given numbers are 990, 623, 30, 662

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

Apply this formula for all numbers.

Step1:

LCM(990, 623) = 616770

GCD(990, 623) = ( 990 x 623 ) / 616770

= 990 / 623

= 990

Step2:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 990, 623, 30, 662 is 1
