Steps to Calculate GCD of 441, 245, 197, 729 using LCM Formula
Given numbers are 441, 245, 197, 729
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 245) = 2205
GCD(441, 245) = ( 441 x 245 ) / 2205
= 441 / 245
= 441
Step2:
LCM(49, 197) = 9653
GCD(49, 197) = ( 49 x 197 ) / 9653
= 49 / 197
= 49
Step3:
LCM(1, 729) = 729
GCD(1, 729) = ( 1 x 729 ) / 729
= 1 / 729
= 1
So, Greatest Common Divisor of 441, 245, 197, 729 is 1
