Steps to Calculate GCD of 811, 395, 70, 389 using LCM Formula
Given numbers are 811, 395, 70, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 395) = 320345
GCD(811, 395) = ( 811 x 395 ) / 320345
= 811 / 395
= 811
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 811, 395, 70, 389 is 1
