Given numbers are 432, 838, 990, 445

The list of prime factors of all numbers are

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 838 are 2 x 419

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

Prime factors of 445 are 5 x 89

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

Given numbers are 432, 838, 990, 445

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

Apply this formula for all numbers.

Step1:

LCM(432, 838) = 181008

GCD(432, 838) = ( 432 x 838 ) / 181008

= 432 / 838

= 432

Step2:

LCM(2, 990) = 990

GCD(2, 990) = ( 2 x 990 ) / 990

= 2 / 990

= 2

Step3:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 432, 838, 990, 445 is 1
