Given numbers are 288, 218, 644, 908

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

Apply this formula for all numbers.

Step1:

LCM(288, 218) = 31392

GCD(288, 218) = ( 288 x 218 ) / 31392

= 288 / 218

= 288

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 908) = 908

GCD(2, 908) = ( 2 x 908 ) / 908

= 2 / 908

= 2

So, Greatest Common Divisor of 288, 218, 644, 908 is 2
