what is the lcm of 440,880
  • Sandeep Reddy Komatireddy

    First write down the facors using factorization technique


    440 = 2^3 * 5^1 * 11 ^1


    880 =2^4 * 5^1 * 11 ^1


    Write down all the facotors and take highst power from 440 or 880


    LCM = 2^4 * 5^1 * 11 ^1 = 880

    There is a short cut method, of all the numbers given in the series (here only two numbers in series), take the common number out. here 440 can be taken out - then what is remaining is 1 & 2


    HCF of440, 880 = 440 * HCF of (1,2) = 440


    LCM of 440, 880 = 440 *LCM (1,2) = 440*2 = 880


    This, of course can be used only if there is some number that you can see can be taken out.
