You can find this number by factoring the digits 1 through 9 into primes, and then finding the least common multiple.
1 = 1
2 = 2
3 = 3
4 = 2*2
5 = 5
6 = 2*3
7 = 7
8 = 2*2*2
9 = 3*3
The 8 requires you to have three 2's, the 9 requires you to have two 3's. All the other primes show up once.
The number you're looking for is:
1*2*2*2*3*3*5*7 = 2520

1 : 1
2 : 1 * 2
3 : 1 * 3
4 : 2 * 2
5 : 1 * 5
6 : 2 * 3
7 : 1 * 7
8 : 2 * 2 * 2
9 : 3 * 3
I get 2520

that is LCM(1,2,3,4,5,6,7,8,9)
let us write a product of prime numbers
4= 2*2
2=2
3=3
5=5
6= 2*3
7=7
8= 2*2*2
9= 3*3
LCM = 3*3*2*2*2*7*5 = 36*7*10 = 2520
this is the answer

Just wanted to say that 840 is wrong, as it is NOT divisible by 9.

What do you mean by "evenly divisible" ? Do you mean "exactly divisible" by even numbers? Or do you simply mean "exactly divisible"?
If you mean exactly divisible, the answer is 2520.
If you truly mean "evenly" divisible, the answer is 5040.

2520
9=3.3
8=2.2.2
7=7.1
6=3.2
5=5.1
4=2.2
3=3.1
2=2.1
1=1.1
cancel 1,2,3,4 and 6 because their prime factors were already contained in 9,8,7 and 5
9*8*7*5=2520
