Steps to Calculate GCD of 515, 723, 18, 394 using LCM Formula
Given numbers are 515, 723, 18, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 723) = 372345
GCD(515, 723) = ( 515 x 723 ) / 372345
= 515 / 723
= 515
Step2:
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
= 1 / 18
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 515, 723, 18, 394 is 1
