Steps to Calculate GCD of 515, 421, 27, 563 using LCM Formula
Given numbers are 515, 421, 27, 563
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 421) = 216815
GCD(515, 421) = ( 515 x 421 ) / 216815
= 515 / 421
= 515
Step2:
LCM(1, 27) = 27
GCD(1, 27) = ( 1 x 27 ) / 27
= 1 / 27
= 1
Step3:
LCM(1, 563) = 563
GCD(1, 563) = ( 1 x 563 ) / 563
= 1 / 563
= 1
So, Greatest Common Divisor of 515, 421, 27, 563 is 1
