Given numbers are 144, 843, 15

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

Apply this formula for all numbers.

Step1:

LCM(144, 843) = 40464

GCD(144, 843) = ( 144 x 843 ) / 40464

= 144 / 843

= 144

Step2:

LCM(3, 15) = 15

GCD(3, 15) = ( 3 x 15 ) / 15

= 3 / 15

= 3

So, Greatest Common Divisor of 144, 843, 15 is 3
