Given numbers are 392, 990, 446, 681

The list of prime factors of all numbers are

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 446 are 2 x 223

Prime factors of 681 are 3 x 227

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

Given numbers are 392, 990, 446, 681

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

Apply this formula for all numbers.

Step1:

LCM(392, 990) = 194040

GCD(392, 990) = ( 392 x 990 ) / 194040

= 392 / 990

= 392

Step2:

LCM(2, 446) = 446

GCD(2, 446) = ( 2 x 446 ) / 446

= 2 / 446

= 2

Step3:

LCM(2, 681) = 1362

GCD(2, 681) = ( 2 x 681 ) / 1362

= 2 / 681

= 2

So, Greatest Common Divisor of 392, 990, 446, 681 is 1
