Steps to Calculate GCD of 409, 809, 652, 681 using LCM Formula
Given numbers are 409, 809, 652, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 809) = 330881
GCD(409, 809) = ( 409 x 809 ) / 330881
= 409 / 809
= 409
Step2:
LCM(1, 652) = 652
GCD(1, 652) = ( 1 x 652 ) / 652
= 1 / 652
= 1
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 409, 809, 652, 681 is 1
