Steps to Calculate GCD of 655, 153, 343, 115 using LCM Formula
Given numbers are 655, 153, 343, 115
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 153) = 100215
GCD(655, 153) = ( 655 x 153 ) / 100215
= 655 / 153
= 655
Step2:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
Step3:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
So, Greatest Common Divisor of 655, 153, 343, 115 is 1
