How to find the smallest number divisible by first n numbers?
Given a number n find the smallest number evenly divisible by each number 1 to n. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. If you observe carefully the ans must be the LCM of the numbers 1 to n . Initialize ans = 1. Iterate over all the numbers from i = 1 to i = n.
Which is the smallest number which when increased by 11 is exactly?
540–11 = 529. So 529 is the smallest number which when increased by 11 will be divisible by 15, 20 and 54. Collecting factors with their largest exponents: 5*1 x 2*2 x 3*3 = 5 x 4 x 27 = 540 which is evenly divided by 15, 20 and 54.
How to find the smallest number below 20?
You need to find out what the prime factors of each number below 20 are, and then construct the smallest number that includes the same, and it will be the answer.
Can you check all numbers that are divisible by 20?
However, you don’t have to check all numbers 1..20. If a number is divisible by 20, it is divisible by 2, 5, 10. Extending this, it would be sufficient to check only divisors from 11..20. Another simple thing would be to increase the candidate solutions by 20 ( number += 20) instead of 1, since any other number would not be divisible by 20.
