Given numbers are 672, 798, 375, 645

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

Apply this formula for all numbers.

Step1:

LCM(672, 798) = 12768

GCD(672, 798) = ( 672 x 798 ) / 12768

= 672 / 798

= 672

Step2:

LCM(42, 375) = 5250

GCD(42, 375) = ( 42 x 375 ) / 5250

= 42 / 375

= 42

Step3:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

So, Greatest Common Divisor of 672, 798, 375, 645 is 3
