GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 387) = 95976
GCD(744, 387) = ( 744 x 387 ) / 95976
= 744 / 387
= 744
Step2:
LCM(3, 390) = 390
GCD(3, 390) = ( 3 x 390 ) / 390
= 3 / 390
= 3
Step3:
LCM(3, 312) = 312
GCD(3, 312) = ( 3 x 312 ) / 312
= 3 / 312
= 3
So, Greatest Common Divisor of 744, 387, 390, 312 is 3
