Steps to Calculate GCD of 489, 692, 55, 238 using LCM Formula
Given numbers are 489, 692, 55, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 692) = 338388
GCD(489, 692) = ( 489 x 692 ) / 338388
= 489 / 692
= 489
Step2:
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
= 1 / 55
= 1
Step3:
LCM(1, 238) = 238
GCD(1, 238) = ( 1 x 238 ) / 238
= 1 / 238
= 1
So, Greatest Common Divisor of 489, 692, 55, 238 is 1
