## Is the product of k consecutive positive integers divisible by K?

The product of k consecutive positive integers is divisible by n for each positive integer n<=k. Unfortunately this has no direct implication for divisibility by k!.

## How can I prove that the product of any 4 consecutive integers is divisible by 24?

# 2, 3, 4, 5 product = 120 and 120 is divisible by 24 exactly that is (120)/(24) = 5 exactly. # 3, 4, 5, 6 product = 360 and 360 is divisible by 24 exactly such that (360)/(24) = 15 exactly. We have therefore proved that the product of 4 consecutive integers is EXACTLY DIVISIBLE by 24.

**What is a consecutive negative integer?**

Consecutive integers are integers that follow each other in order. We will illustrate with good examples. Look at the following two sets. The first two are called consecutive positive integer. The last two are called consecutive negative integers.

**How do you find consecutive factors of a number?**

266 Why 8 Consecutive Numbers with 6 Factors is Impossible

- 266 is a composite number.
- Prime factorization: 266 = 2 x 7 x 19.
- The exponents in the prime factorization are 1, 1, and 1.
- Factors of 266: 1, 2, 7, 14, 19, 38, 133, 266.
- Factor pairs: 265 = 1 x 266, 2 x 133, 7 x 38, or 14 x 19.

### What is the product of 4 consecutive integers?

The product of 4 consecutive natural numbers is 5040. Find those numbers. Hint: We know that consecutive numbers are the number which follow each other in order, without any gap like 22,24,26,28 are the example of consecutive even numbers. Similarly we will find 4 consecutive natural numbers as n, n+1, n+2 and n+3.

### How do you find the product of k consecutive integers?

The product of k consecutive integers is divisible by k!, in particular by k (provided k ≥ 1 ). ( n k) = n ( n − 1) … ( n − k + 1) k! is the number of ways to choose k elements from n, which is obviously an integer. Let us assume that we have k consecutive integers with the first one of them being n.

**How do you prove that a sum is divisible by K?**

Now the proof by induction over k goes through easily: Base: If k = 0, we have that 0! ∣ m 0 _, which is just 1 ∣ 1. Induction: Assume k! ∣ m k _ for all m. Then: By induction, each term of the sum is divisible by k!, so the right hand side is divisible by ( k + 1) k! = ( k + 1)!.

**What is the product of k consecutive posints starting with M?**

THEOREM: Product of k consecutive posints starting with m is divisible by k factorial (i) BASIS: If n = 2 then clearly m=k=1 and we have k! = 1! clearly divides P (m,k) = 1 (ii) INDUCTION STEP: Assume k! | P (m,k) for all m+k<=n.

## Why do we divide by two successive numbers on K?

Simply because the multiplication to a number process is just a summation ( walking steps ) and the distance between any two successive divisible numbers is just the number that we want to divide on. So, when we want to divide K successive numbers on K we will get a divisible number on K between those numbers.
