Steps to Calculate GCD of 413, 809, 345, 391 using LCM Formula
Given numbers are 413, 809, 345, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(413, 809) = 334117
GCD(413, 809) = ( 413 x 809 ) / 334117
= 413 / 809
= 413
Step2:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 413, 809, 345, 391 is 1
