Given numbers are 430, 577, 445, 990

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 577 are 577

Prime factors of 445 are 5 x 89

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

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

Given numbers are 430, 577, 445, 990

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

Apply this formula for all numbers.

Step1:

LCM(430, 577) = 248110

GCD(430, 577) = ( 430 x 577 ) / 248110

= 430 / 577

= 430

Step2:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 430, 577, 445, 990 is 1
