GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 606) = 29694
GCD(147, 606) = ( 147 x 606 ) / 29694
= 147 / 606
= 147
Step2:
LCM(3, 390) = 390
GCD(3, 390) = ( 3 x 390 ) / 390
= 3 / 390
= 3
Step3:
LCM(3, 285) = 285
GCD(3, 285) = ( 3 x 285 ) / 285
= 3 / 285
= 3
So, Greatest Common Divisor of 147, 606, 390, 285 is 3
