Multiply all primes from 1 to 10 (some primes you will need to use more than once). To get the smallest number which is divisible by all digits 1-10, make sure you don't include duplicates. If a number is divisible by 2 and 3, it is divisible by 6.

Write out the numbers, like in factorial form:

10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

Get rid of 10, which is 5 * 2. Get rid of 8 by the previous logic. Also get rid of 9, which is just 3 * 6/2. Get rid of 2, which is (4/2) * 1. Can't get rid of 4, because it's 2 * 2. Can't get rid of 6, because we've used it to get rid of 9. So the numbers 1, 3, 4, 5, 6 and 7 stay in the expression.

1 * 3 * 4 * 5 * 6 * 7 = 2,520

I suppose you want the samaller number else you multiply all the digits and have the number

the number is 1*5*7*8*9= 2520

i did not include 2and 4 since a number divisble by 8 is also divisble by 2and 4 so, for 3

An easy way is imply to multiply all the numbers from 1 to 10 together, giving 3628800.
There may well be other numbers that fit the bill as well though.

LCM of all numbers from 1 to 10 is 2520.
So the number will be 2520.

The smallest number divisible by 1,2,3,4,5,6,7,8,9 and 10 will be their LCM or lowest common multiple, which is 2520.

There are several such numbers (an inifinte number in fact).

However, the lowest number is 2520 (I think)

1 * 2520
2 * 1260
3 * 840
4 * 630
5 * 504
6 * 420
7 * 360
8 * 315
9 * 280
10 * 252
