Steps to Calculate GCD of 155, 305, 563, 385 using LCM Formula
Given numbers are 155, 305, 563, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 305) = 9455
GCD(155, 305) = ( 155 x 305 ) / 9455
= 155 / 305
= 155
Step2:
LCM(5, 563) = 2815
GCD(5, 563) = ( 5 x 563 ) / 2815
= 5 / 563
= 5
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 155, 305, 563, 385 is 1
