Steps to Calculate GCD of 815, 205, 663, 498 using LCM Formula
Given numbers are 815, 205, 663, 498
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 205) = 33415
GCD(815, 205) = ( 815 x 205 ) / 33415
= 815 / 205
= 815
Step2:
LCM(5, 663) = 3315
GCD(5, 663) = ( 5 x 663 ) / 3315
= 5 / 663
= 5
Step3:
LCM(1, 498) = 498
GCD(1, 498) = ( 1 x 498 ) / 498
= 1 / 498
= 1
So, Greatest Common Divisor of 815, 205, 663, 498 is 1
