A number has a factor of 10 if the last digit is 0
That is correct. If the last digit of a number is 0, it indicates that it is divisible by 10.
To determine if a number has a factor of 10, you need to check if the last digit of the number is 0. Here's a step-by-step process to follow:
1. Take the number that you want to check for a factor of 10.
2. Look at the last digit of the number.
3. If the last digit is 0, then the number has a factor of 10.
4. If the last digit is not 0, then the number does not have a factor of 10.
For example, let's say we have the number 350. Following the steps:
1. The number we want to check is 350.
2. The last digit of 350 is 0.
3. Since the last digit is 0, 350 has a factor of 10.
On the other hand, if we have the number 384:
1. The number we want to check is 384.
2. The last digit of 384 is 4.
3. Since the last digit is not 0, 384 does not have a factor of 10.
To check if a number has a factor of 10, you can simply examine the last digit of the number. If the last digit is 0, then the number is divisible by 10 and therefore has a factor of 10.
To find the last digit of a number, you can take the remainder of the number when divided by 10. This can be done using the modulus operator (%). For example, if you have the number 150, you can find the last digit by calculating 150 % 10, which equals 0. Hence, 150 has a factor of 10.
Similarly, for any number, you can check if it has a factor of 10 by taking the remainder when divided by 10. If the remainder is 0, then the number has a factor of 10. Otherwise, it does not.
