Which of the following is a multiple of both 3 and 5?
15 and 30 are common multiples of 3 and 5. Any two numbers have an infinite amount of common multiples. A trick to find common multiples for two numbers is to multiply the two numbers together and find the multiples of that number.
What are the multiples of 3 and 5?
How do you find the sum of multiples of 3?
1 Expert Answer The series sum of an arithmetic sequence is n( average of first and last term) So for the multiples of three this is 33(3 + 99)/2 = 1683. The sum of the natural numbers less than 100 is, by the same formula, 99(1 + 99)/2 = 4950. The desired sum is the difference 4950 – 1683 = 3267.
What is the sum of all numbers between 1 and 1000?
What is the sum of all multiples of 5 between 1 and 100?
the sum of all the integers that are multiples of 5 from 1 to 100 is 5 x 210 = 1050.
Which of the groups of numbers below are multiples of 5?
The multiples of 5 include 5, 10, 15, 20, 25, 30, 35, 40,….
What is the total number of digits from 1 to 1000?
Now let us look at the numbers from 1 to 1000. To write all these numbers down, we need to use 9 + 180 + 2700 + 4 = 2893 digits to accommodate the 9 single-digit numbers, the 90 double-digit numbers, the 900 triple-digit numbers and the number 1000. How may zeros did we need?
How do you find the multiples of 3 and 5 below 1000?
Find the sum of all the multiples of 3 or 5 below 1000. The previously posted answer isn’t correct. The statement of the problem is to sum the multiples of 3 and 5 below 1000, not up to and equal 1000. The correct answer is ∑ k = 1 n k = 1 2 n ( n + 1).
What is the sum of the first few multiples of 5?
The multiples of 5 are 5,10,15,20,25,30,35,40,45,…. The intersection of these two sequences is 15,30,45,… The sum of the first numbers 1+2+3+4+…+n is n(n+1)/2. The sum of the first few multiples of k, say k+2k+3k+4k+…+nk must be kn(n+1)/2. Now you can just put these ingredients together to solve the problem.
What is the sum of the multiples of 1 to K?
= 3 * (333 * 334 / 2) because the sum of the integers from 1 to k is k* (k+1)/2. Use the same logic for the sum of multiples of 5 and 15.
What is the sum of 3 and 5 divided by 15?
Well, the answer is, 15 can be evenly divide by both 3 & 5. So the products of 15 can also be divided by those number as well! So, when you adding the numbers with Sum Of Three & Sum Of Five there are some numbers (i.e. 15,30,45,60….) which are available at both SUMMATION.
