Find the least number divisible by each natural number less than or equal to 10.

  • Math -

    These are the possible answers
    A) 100 B) 3,628,800 C) 2520 D) 30,240
    I don't understand this question at all. Do you?

    2
    3
    2x2
    5
    2x3
    7
    2x2x2
    3x3
    2x5

    so we need 2x2x2x3x3x5x7 = 504

    This is just like finding the LCD for
    1 + 1/2 + 1/3 + ... + 19 + 110

    I see what you are saying, and thank you for trying to explain. What I am confused about is none of the answers anyone has given me is a possible answer in my multiple choice options.

    A) 100
    b) 3,628,800
    c) 2520
    d) 30,240

    You breaking it down as the LCD has made the most sense. But do you see the dilema with the choice options?

    Thanks, the product of my factors is <b.2520 , and not 504

    I must have missed the 5 in my multiplication.

    Sorry about the silly arithmetic error, amazing how we all depend on our calculators
