Steps to Calculate GCD of 387, 489, 573, 905 using LCM Formula
Given numbers are 387, 489, 573, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 489) = 63081
GCD(387, 489) = ( 387 x 489 ) / 63081
= 387 / 489
= 387
Step2:
LCM(3, 573) = 573
GCD(3, 573) = ( 3 x 573 ) / 573
= 3 / 573
= 3
Step3:
LCM(3, 905) = 2715
GCD(3, 905) = ( 3 x 905 ) / 2715
= 3 / 905
= 3
So, Greatest Common Divisor of 387, 489, 573, 905 is 1
