Given numbers are 990, 728, 451, 730

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 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 451 are 11 x 41

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 990, 728, 451, 730

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

Apply this formula for all numbers.

Step1:

LCM(990, 728) = 360360

GCD(990, 728) = ( 990 x 728 ) / 360360

= 990 / 728

= 990

Step2:

LCM(2, 451) = 902

GCD(2, 451) = ( 2 x 451 ) / 902

= 2 / 451

= 2

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 990, 728, 451, 730 is 1
