Steps to Calculate GCD of 231, 365, 145, 809 using LCM Formula
Given numbers are 231, 365, 145, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 365) = 84315
GCD(231, 365) = ( 231 x 365 ) / 84315
= 231 / 365
= 231
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 231, 365, 145, 809 is 1
