Steps to Calculate GCD of 678, 213, 489, 757 using LCM Formula
Given numbers are 678, 213, 489, 757
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 213) = 48138
GCD(678, 213) = ( 678 x 213 ) / 48138
= 678 / 213
= 678
Step2:
LCM(3, 489) = 489
GCD(3, 489) = ( 3 x 489 ) / 489
= 3 / 489
= 3
Step3:
LCM(3, 757) = 2271
GCD(3, 757) = ( 3 x 757 ) / 2271
= 3 / 757
= 3
So, Greatest Common Divisor of 678, 213, 489, 757 is 1
