Given numbers are 574, 282, 720, 645

The list of prime factors of all numbers are

Prime factors of 574 are 2 x 7 x 41

Prime factors of 282 are 2 x 3 x 47

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 574, 282, 720, 645

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

Apply this formula for all numbers.

Step1:

LCM(574, 282) = 80934

GCD(574, 282) = ( 574 x 282 ) / 80934

= 574 / 282

= 574

Step2:

LCM(2, 720) = 720

GCD(2, 720) = ( 2 x 720 ) / 720

= 2 / 720

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 574, 282, 720, 645 is 1
