Steps to Calculate GCD of 289, 447, 631, 245 using LCM Formula
Given numbers are 289, 447, 631, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 447) = 129183
GCD(289, 447) = ( 289 x 447 ) / 129183
= 289 / 447
= 289
Step2:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 289, 447, 631, 245 is 1
