Given numbers are 445, 304, 749, 420

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

Prime factors of 749 are 7 x 107

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 445, 304, 749, 420

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

Apply this formula for all numbers.

Step1:

LCM(445, 304) = 135280

GCD(445, 304) = ( 445 x 304 ) / 135280

= 445 / 304

= 445

Step2:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 445, 304, 749, 420 is 1
