Steps to Calculate GCD of 423, 489, 818, 615 using LCM Formula
Given numbers are 423, 489, 818, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 489) = 68949
GCD(423, 489) = ( 423 x 489 ) / 68949
= 423 / 489
= 423
Step2:
LCM(3, 818) = 2454
GCD(3, 818) = ( 3 x 818 ) / 2454
= 3 / 818
= 3
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 423, 489, 818, 615 is 1
