is there a way how to find how many numbers are divisible by 60r 10 or both?

Question

i MEAN 6 or 10

My question was... (im sorry) ..how many numbers from 1 through 1000 are divisible by 6 or 10 (or both)

Answer 1

If the number ends in a "0" it is divisible by 10.

If you add all the digits and the total is divisible by "3" the number is divisible by 3. (i.e. 126 = 1 + 2 + 6 =r 9. 9 is divisible by 3 -- and so is 126.

If a number that is divisible by 3 is also even (0, 2,4, 6, 8) it is divisible by 6.

If all of the above are true, then the number would be divisible by 60.

Based on your edit of your question:
Between 1-1,000, there are 100 numbers divisible by 10. (1000 divided by 10.)
There are 166 numbers divisible by 6. (1000 divided by 6, rounded down)
There are 16 numbers divisible by 60. (1,000 divided by 60, rounded down.

If you have Excel or another spreadsheet, test it. 60, 120, 180, and so on until you get to 1,000. Or you can do it manually, just write down all the numbers and then count them.

Answer 2

60 is divisible by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 (12 numbers)

10 is divisible by 1, 2, 5, 10 (4 numbers)

To find out what numbers a certain number is divisible by, you have to see which number will go into that main number evenly (using division)...starting with 1 and working your way up to that number.

Is this what you were asking for?
