Steps to Calculate GCD of 289, 138, 207, 571 using LCM Formula
Given numbers are 289, 138, 207, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 138) = 39882
GCD(289, 138) = ( 289 x 138 ) / 39882
= 289 / 138
= 289
Step2:
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
= 1 / 207
= 1
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 289, 138, 207, 571 is 1
