Is 19 a multiple of 3?
No. To check if a number is a multiple of 3 add its digits together and if this sum is a multiple of 3, then so is the original number. This sum can be continued until a single digit remains; if the single digit is 3, 6 or 9 then the original number is a multiple of 3, otherwise not. 19 → 1 + 9 = 10 10 → 1 + 0 = 1 which is not 3, 6 or 9, so 19 is not a multiple of 3.
How can you tell that 189 is divisible by 3 without doing the division?
Add up the digits in a number, and if that sum is a multiple of 3, then the original number is also a multiple of 3. So 1 + 8 + 9 = 18, which if you're still not sure then 1+8=9, which is a multiple of 3. You can repetitively sum the digits until you have a result of a single digit number. If the single digit result is 3,6 or 9, then the original number is a multiple of 3. Also, if the single digit number is 9, then the number is also a multiple of 9. However, if the result is 6, then it is not necessarily a multiple of six.
Why a number that ends in a 3 can't be a multiple of 4?
The digit with which a multiple of 4 ends depends on the last digit of the other factor. If the last digit is a zero, the product ends with zero; if the last digit is a 1, the product ends with 4; etc. The only options for the last digit of the product are 0, 2, 4, 6, 8.
How do you decide if a two-digit number is a multiple of a one digit number?
Divide the 2-digit number by the 1-digit number. If the quotient comes out a whole number, then the big one is a multiple of the small one.
What is a 3 digit number that is divisible by 1?
a 3 digit number that is divisible by on is a three digit number that is a multiple of one.
How do you decide if a two digit number is a multiple of a one digit number?
Without putting too much thought into it, you can just try dividing your two digit number by each and see if you come up with a whole number. One digit numbers you can skip are 0, 1, 4, 6, 8, and 9.
What is the smallest digit number that is a multiple of 15?
It is: 1

When a number is a multiple of 5, the possible values for the ones digit are zero and five.
What is a 2 digit number a multiple of 8 the sum of its digits is 9?
8 and 1

When you divide a 3 digit number by a 1 digit number will the answer ever be a 1 digit number?
No.
What number is both a factor AND a multiple of six?
The largest two-digit multiple of six is 96.
What two-digit number is a multiple of 3 and 7 and is 1 less than the multiple of 5?
A two-digit number that is a multiple of 3 and 7 and 1 less than a multiple of 5 is 84, because 84/7=12 and 84/3=28 and 84 is 1 less than 85, and 85 is a multiple of 5 so the answer is 84
What are 2-digit multiples of 5?
-3
