GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(243, 489) = 39609
GCD(243, 489) = ( 243 x 489 ) / 39609
= 243 / 489
= 243
Step2:
LCM(3, 858) = 858
GCD(3, 858) = ( 3 x 858 ) / 858
= 3 / 858
= 3
Step3:
LCM(3, 140) = 420
GCD(3, 140) = ( 3 x 140 ) / 420
= 3 / 140
= 3
So, Greatest Common Divisor of 243, 489, 858, 140 is 1
