What is the sum of all three digit multiples of 3 or 5?
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
What is a sum of 3 and 5?
3, 6, 9, 12, 15 which is same as 3 multiplied by the first 5 integers (1, 2, 3, 4, 5). We know the sum of first 5 integers as 5 * 4/2 = 10. So, the sum of first 5 multiples of 3 is 3 * 10 that is 30.
What is the sum of all the multiples of 3 or 5 below 1000 Python?
The answer is 233168, so the second solution is closer.
What are the first five multiples of 3 and 5?
Solution: Let us multiply 5 with the first 3 numbers 1, 2, and 3. Hence, the first 3 multiples of 5 are 5, 10, and 15.
How do you find the sum of multiple numbers?
Multiply the amount of numbers in the series by the sum obtained from each column addition. For example, you multiply 10, the amount of numbers from one to 10, by the average sum of 11, obtaining 110. Divide the product by two. For example divide, 110 by two.
What is the sum of all three digit multiples of 7?
70336
Hence, the sum of all three-digit natural numbers, which are multiples of 7 is 70336.
What is the sum of 5 by 3 3 by 5?

How do you find the sum of multiples?
Originally Answered: How do I get sum of multiples of 3 between 1 to 100? So, we have the first term as 3, common difference as 3 and number of terms as 33, just put them into the formula S= n(2a + (n-1)d)/2 where n=number of terms, a=first term and d=common difference, to get the answer as 1683.
What is the sum of all the multiples of 3 and 5 below 100?

How to find Count of multiples of 3 or 5 in given range?
Similarly, the count of the number which is divisible by 5 in the given range is equal to the floor (n/5). In the range 1-20 count number divisible by 5 are floor (20/5)=4 i.e. { 5,10,15,20}. And count of the number which is divisible by 3 and 5 in the given range is equal to the floor (n/3)+floor (n/5)-floor (n/15).
