Steps to Calculate GCD of 397, 213, 289, 545 using LCM Formula
Given numbers are 397, 213, 289, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 213) = 84561
GCD(397, 213) = ( 397 x 213 ) / 84561
= 397 / 213
= 397
Step2:
LCM(1, 289) = 289
GCD(1, 289) = ( 1 x 289 ) / 289
= 1 / 289
= 1
Step3:
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
= 1 / 545
= 1
So, Greatest Common Divisor of 397, 213, 289, 545 is 1
