Given numbers are 656, 378, 288, 345

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

Apply this formula for all numbers.

Step1:

LCM(656, 378) = 123984

GCD(656, 378) = ( 656 x 378 ) / 123984

= 656 / 378

= 656

Step2:

LCM(2, 288) = 288

GCD(2, 288) = ( 2 x 288 ) / 288

= 2 / 288

= 2

Step3:

LCM(2, 345) = 690

GCD(2, 345) = ( 2 x 345 ) / 690

= 2 / 345

= 2

So, Greatest Common Divisor of 656, 378, 288, 345 is 1
