Steps to Calculate GCD of 289, 657, 481, 154 using LCM Formula
Given numbers are 289, 657, 481, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 657) = 189873
GCD(289, 657) = ( 289 x 657 ) / 189873
= 289 / 657
= 289
Step2:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 289, 657, 481, 154 is 1
