The sum of these multiples is . We won't just give you a solution - what would you learn if we did? The sum of these multiples is 23. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. If a box contains twenty-one coloured discs, composed of fifteen blue discs and six red discs, and two discs were taken at random, it can be seen that the probability of taking two blue discs, P(BB) = (15/21)×(14/20) = 1/2.

The series, 1 1 + 2 2 + 3 3 + … + 10 10 = 10405071317.. Find the last ten digits of the series, 1 1 + 2 2 + 3 3 + … + 1000 1000.. Find the sum of all the multiples of 3 or 5 below 1000. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. … Problem 48 of Project Euler has the nice and simple description. Problem. Solution Obvious solution. Please be sure to answer the question. – Fabinout Jan 29 '14 at 16:24 Leaderboard. The sum of these multiples is 23. ... but it was the Project Euler forums that showed me the formula to do it. Since you have a generalized solution, you should provide your generalized specification of the problem. Project Euler Problem 1 Statement. \$\begingroup\$ BTW it would be best to include the specification of the project Euler problem 1 in your question if you implemented the problem solution as stated in project euler. Project Euler (projecteuler.net) is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. This problem is a programming version of Problem 1 from projecteuler.net. Active today. Discussions. Question 1: If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. Viewed 11 times 1 $\begingroup$ Okay so the problem itself is really simple, If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9.
