Steps to Calculate GCD of 159, 431, 905, 217 using LCM Formula
Given numbers are 159, 431, 905, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 431) = 68529
GCD(159, 431) = ( 159 x 431 ) / 68529
= 159 / 431
= 159
Step2:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
Step3:
LCM(1, 217) = 217
GCD(1, 217) = ( 1 x 217 ) / 217
= 1 / 217
= 1
So, Greatest Common Divisor of 159, 431, 905, 217 is 1
