Given numbers are 990, 681, 368, 663

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 681 are 3 x 227

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 990, 681, 368, 663

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

Apply this formula for all numbers.

Step1:

LCM(990, 681) = 224730

GCD(990, 681) = ( 990 x 681 ) / 224730

= 990 / 681

= 990

Step2:

LCM(3, 368) = 1104

GCD(3, 368) = ( 3 x 368 ) / 1104

= 3 / 368

= 3

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 990, 681, 368, 663 is 1
