So we stop the process and continue dividing the number 525 by the next smallest prime factor. You need to optimize your algorithm, not your implementation of a bad algorithm. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Note : Also 1, -24, -2, 12, 3 , 8, -6 and -4 are also factors of 24 . Example 4: Find the product of all the prime factors of 4200. Solution: We know that the smallest and the largest odd numbers in the range of 1 to 1000 are 1 and 999 respectively. Not the answer you're looking for? Step 3: Calculate the final answer. = 5 x 49 x 25 x 4. Calculat. Time Complexity: O(sqrt(N)) // since there is one loop and it goes till the square root of the length of the array thus time complexity is O(sqrt(N))Auxiliary Space: O(1) // since there is no extra array involved thus it takes constant spaceEfficient Solution:The following observation must be made to optimize the above approach: N = P1A1 * P2A2 * P3A3 * .. * PkAK where, each Pi is a prime and each Ai is a positive integer. Solution : Prime Factorization of 120 is 120 = 23 31 51. 4200/15 = 280; therefore, 15 is a factor of 4200 and 280 is also a factor of 4200.

Example 3. A can do a piece of work in 22 days while B alone can complete the whole work in 26 days. But we have to exclude 1 and 10500, So there are only 48-2 = 46 positive factors of 10500 except 1 and itself. 728.821/3+1155.98 + 6.142 2.992+ 1.970=? It means only an even number can have an even and an odd factors whereas an odd number has only odd factors. We want ODD factors of 1200. In these factors, you found that 1, 3, 5, 9, 15, 27, 45, 135, all are the ODD factors of 135. Every factor of 1200 is the product of some subset of these numbers. Hence, the total odd factors = (3 + 1) * (2 + 1) = 12. 1200/150 = 8; therefore, 150 is a factor of 1200 and 8 is also a factor of 1200. Calculating the total number of even and odd factors of number 48.2. 651, 653, 655, 657, 659, 661, 663, 665, 667, 669, 671, 673, 675, 677, 679, 681, 683, 685, 687, 689, 691, 693, 695, 697, 699. is ax by cz where a, b, c are prime, Prime Factorization of 4200 = 23 31 52 71 How to find the sum of largest odd factor of a number? The exam is scheduled to be held in the month of November-December 2023. How many odd factors does 180 have? When we divide 4200 by 983 it leaves a remainder. By applying the formulae, Sum of factors = [ (2 0 +2 1 +2 2 +2 3 ) (3 0 +3 1 ) (5 0 +5 1 )]/ [ (2-1) (3-1) (5-1)] = 45 Number of factors = (3+1) (1+1) (1+1) = 16 Product of factors = 120 (16/2) = 120 8 Example 2: Find the following for the number 84 :- Number of odd factors The factors of 4200 are too many, therefore if we can find the prime factorization of 4200, All the odd numbers between 1 to 1000 that have more than two factors or the numbers that are not prime are known as odd composite numbers in this range, such as 9, 15, 999, etc. (1) Thus, Total number of factors of 150 is (1 + 1) (1 + 1) (2 + 1) = 2 2 3 = 12.
