Given numbers are 645, 125, 300, 336

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 125 are 5 x 5 x 5

Prime factors of 300 are 2 x 2 x 3 x 5 x 5

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 645, 125, 300, 336

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

Apply this formula for all numbers.

Step1:

LCM(645, 125) = 16125

GCD(645, 125) = ( 645 x 125 ) / 16125

= 645 / 125

= 645

Step2:

LCM(5, 300) = 300

GCD(5, 300) = ( 5 x 300 ) / 300

= 5 / 300

= 5

Step3:

LCM(5, 336) = 1680

GCD(5, 336) = ( 5 x 336 ) / 1680

= 5 / 336

= 5

So, Greatest Common Divisor of 645, 125, 300, 336 is 1
