  • there is an easy er way

  • @hamza6415 You know of an easier way? Or the way I showed in the video is the easy way?

  • Thanks akeel456!

    I will put a few more up here soon. In the meantime be sure to check my website for newer videos if you like these ones.

  • A real easy way is to factor out both denominators.

    8 = 2^3. 12 = 2^2 x 3.

    Now pull out each prime number with the largest exponent you see. So we would have 2^3 and a 3.

    Multiply these two terms together. 2^3 = 8.

    8 x 3 = 24, and that is your LCD.

    Let me know if you still need more help.

  • Thanks!

see all
