Steps to Calculate GCD of 217, 347, 215, 203 using LCM Formula
Given numbers are 217, 347, 215, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 347) = 75299
GCD(217, 347) = ( 217 x 347 ) / 75299
= 217 / 347
= 217
Step2:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
Step3:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 217, 347, 215, 203 is 1
