Steps to Calculate GCD of 489, 543, 148, 665 using LCM Formula
Given numbers are 489, 543, 148, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 543) = 88509
GCD(489, 543) = ( 489 x 543 ) / 88509
= 489 / 543
= 489
Step2:
LCM(3, 148) = 444
GCD(3, 148) = ( 3 x 148 ) / 444
= 3 / 148
= 3
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 489, 543, 148, 665 is 1
