GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 308) = 21252
GCD(138, 308) = ( 138 x 308 ) / 21252
= 138 / 308
= 138
Step2:
LCM(2, 470) = 470
GCD(2, 470) = ( 2 x 470 ) / 470
= 2 / 470
= 2
Step3:
LCM(2, 294) = 294
GCD(2, 294) = ( 2 x 294 ) / 294
= 2 / 294
= 2
So, Greatest Common Divisor of 138, 308, 470, 294 is 2
