No, but I suspect you want to know if 810 is divisible by those numbers. Out of that group, 810 is divisible by 2, 3, 5, 6, 9 and 10
no
No
810 is divisible by 3. No need to do anything to it.
Yes. 810 is divisible by these numbers: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810.
Clearly, both 810 and 910 are divisible by 5. A wee trick regarding numbers that are a multiple of 3, is that the component numbers, when added together, are divisible by three. So, 654 is divisible by 3, as 6+5+4 = 15 which is divisible by 3. In your example, 810 components add up to 9, which is divisible by 3. But the components of 910 add up to 10 which is not so divisible.
1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
2 yes 3 yes 4 no 5 yes 6 yes 9 yes 10 yes
Yes.
1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
40,500 810 x 50 = 405 x 100 -------------------------------------------- I suspect that there is a missing slash between the 8 and 10, ie you are asking: What is 8 over 10 of 50? 8/10 × 50 = 40.
It is divisible by 2 and 3. It isn't divisible by 5 and 10.
