Steps to Calculate GCD of 407, 154, 18, 633 using LCM Formula
Given numbers are 407, 154, 18, 633
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 154) = 5698
GCD(407, 154) = ( 407 x 154 ) / 5698
= 407 / 154
= 407
Step2:
LCM(11, 18) = 198
GCD(11, 18) = ( 11 x 18 ) / 198
= 11 / 18
= 11
Step3:
LCM(1, 633) = 633
GCD(1, 633) = ( 1 x 633 ) / 633
= 1 / 633
= 1
So, Greatest Common Divisor of 407, 154, 18, 633 is 1
