Given numbers are 645, 276, 574, 285

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 574 are 2 x 7 x 41

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 645, 276, 574, 285

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

Apply this formula for all numbers.

Step1:

LCM(645, 276) = 59340

GCD(645, 276) = ( 645 x 276 ) / 59340

= 645 / 276

= 645

Step2:

LCM(3, 574) = 1722

GCD(3, 574) = ( 3 x 574 ) / 1722

= 3 / 574

= 3

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 645, 276, 574, 285 is 1
