If the one's digit of a number greater than 1 is 10,what factor or factors must that number have

no digit can be 10.

No

If the one's digit of a number is 10, it means that the number itself is a multiple of 10. In other words, it must be divisible by 10.

To understand why this is the case, we need to look at the concept of place value in our number system. The digit in the one's place represents the value of the number modulo 10. When the one's digit is 10, it means that the number can be expressed as a multiple of 10 plus 10 itself.

For example, let's consider the number 40. The digit in the one's place is 0, which signifies that the number is divisible by 10. In this case, 40 = 4 * 10 + 0.

Similarly, if the one's digit is 10, it means that the number can be expressed as a multiple of 10 plus 10. For instance, 110 = 11 * 10 + 10, and 910 = 91 * 10 + 10.

Therefore, if the one's digit of a number is 10, the number itself must be a multiple of 10 and therefore divisible by 10.
