Steps to Calculate GCD of 231, 511, 423, 399 using LCM Formula
Given numbers are 231, 511, 423, 399
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 511) = 16863
GCD(231, 511) = ( 231 x 511 ) / 16863
= 231 / 511
= 231
Step2:
LCM(7, 423) = 2961
GCD(7, 423) = ( 7 x 423 ) / 2961
= 7 / 423
= 7
Step3:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
So, Greatest Common Divisor of 231, 511, 423, 399 is 1
