Given numbers are 612, 840, 445, 230

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 445 are 5 x 89

Prime factors of 230 are 2 x 5 x 23

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

Given numbers are 612, 840, 445, 230

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

Apply this formula for all numbers.

Step1:

LCM(612, 840) = 42840

GCD(612, 840) = ( 612 x 840 ) / 42840

= 612 / 840

= 612

Step2:

LCM(12, 445) = 5340

GCD(12, 445) = ( 12 x 445 ) / 5340

= 12 / 445

= 12

Step3:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

So, Greatest Common Divisor of 612, 840, 445, 230 is 1
