In this python programming tutorial, we will learn how to find all numbers that are divisible by two specific numbers. For example, let's take a look at the list [1,2,3,4,5]. In this list, numbers that are divisible by 2 and 1 are [2,4]. Our program will do the same thing. The user will enter the values of the list and also the two numbers (let's say m and n) Find the largest number, which exactly divides every number of the form $(n^{3}- n) ( n -2)$ where n is a natural number greater than 2. 2. How many numbers between 1000 and 5000 are exactly divisible by 22 [7.5] The sum of part of the series of natural numbers from n 1 to n 2 is the sum from 1 to n 2-1 less the sum from 1 to n 2. [7.6] Substituting the formula for the first n natural numbers in 7.6, we get: [7.7] Which gives us: [7.8] Collecting like terms: [7.9] Factorising gives us the formula for the series of natural numbers from n 1 to n 2

The number of zeroes would be given by adding the quotients when we successively divide 1090 by 5: 1090/5 + 218/5 + 43/5 + 8/5 = 218 + 43 + 8 + 1 = 270 Q. If 146! is divisible by 5 n , then find the maximum value of n Lowest two digit number divisible by 3 is 12 Highest two digit number divisible by 3 We know that 99/3 = 33 ∴ Highest two digit number divisible by 3 is 99 So, the series starts with 12 and ends with 99 Since the number is less than 1000, it could be a three-digit, two-digit or single-digit number. Case I: Three-digit number: Now, the hundred's place cannot be zero. Thus, it can be filled with three digits, i.e. 3, 5 and 7. Also, the unit's place cannot be zero Let p be a prime number greater than 5. Then (p^2 - 1) is. A positive integer is said to be a prime number if it is not divisible by any positive integer other than itself and 1. Let p be a prime number greater than 5. Then (p 2 - 1) is. always divisible by 6, and may or may not be divisible by 12; always divisible by 24; never divisible by 4) Find the number of positive integers not exceeding 100 that are not divisible by 5 or by 7. 5) There are 345 students at a college who have taken a course in calculus, 210 who have taken a course in discrete mathematics and 170 who have taken courses in both subjects. a.
