Using digital roots (adding all the digits in a number up until you get a single digit) we can see that: 105: 1+0+5 = 6 63: 6+3 = 9 If both digital roots equal 3,6,and/or 9 then the LCM is always 3. The Normal Way: A few Multiples of 105: 105 / 5 = 21 21 / 7 = 3 3,5,7,21,105 A few Multiples of 63: 63 / 3 = 21 21 / 7 = 3 3,7,21,63 So as you can see, the LCM is 3.
It is: 630 by finding the prime factors of the given numbers
