Given numbers are 144, 189, 386, 878

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

Apply this formula for all numbers.

Step1:

LCM(144, 189) = 3024

GCD(144, 189) = ( 144 x 189 ) / 3024

= 144 / 189

= 144

Step2:

LCM(9, 386) = 3474

GCD(9, 386) = ( 9 x 386 ) / 3474

= 9 / 386

= 9

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 144, 189, 386, 878 is 1
