Steps to Calculate GCD of 721, 730, 197, 394 using LCM Formula
Given numbers are 721, 730, 197, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 730) = 526330
GCD(721, 730) = ( 721 x 730 ) / 526330
= 721 / 730
= 721
Step2:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 721, 730, 197, 394 is 1
