Given numbers are 645, 728, 153, 573

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 153 are 3 x 3 x 17

Prime factors of 573 are 3 x 191

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

Given numbers are 645, 728, 153, 573

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

Apply this formula for all numbers.

Step1:

LCM(645, 728) = 469560

GCD(645, 728) = ( 645 x 728 ) / 469560

= 645 / 728

= 645

Step2:

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

= 1 / 153

= 1

Step3:

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

= 1 / 573

= 1

So, Greatest Common Divisor of 645, 728, 153, 573 is 1
