Given numbers are 168, 186, 753, 645

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

Apply this formula for all numbers.

Step1:

LCM(168, 186) = 5208

GCD(168, 186) = ( 168 x 186 ) / 5208

= 168 / 186

= 168

Step2:

LCM(6, 753) = 1506

GCD(6, 753) = ( 6 x 753 ) / 1506

= 6 / 753

= 6

Step3:

LCM(3, 645) = 645

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

= 3 / 645

= 3

So, Greatest Common Divisor of 168, 186, 753, 645 is 3
