Given numbers are 120, 645, 470, 473

The list of prime factors of all numbers are

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 645 are 3 x 5 x 43

Prime factors of 470 are 2 x 5 x 47

Prime factors of 473 are 11 x 43

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

Given numbers are 120, 645, 470, 473

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

Apply this formula for all numbers.

Step1:

LCM(120, 645) = 5160

GCD(120, 645) = ( 120 x 645 ) / 5160

= 120 / 645

= 120

Step2:

LCM(15, 470) = 1410

GCD(15, 470) = ( 15 x 470 ) / 1410

= 15 / 470

= 15

Step3:

LCM(5, 473) = 2365

GCD(5, 473) = ( 5 x 473 ) / 2365

= 5 / 473

= 5

So, Greatest Common Divisor of 120, 645, 470, 473 is 1
