Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc.
All generated numbers will be guaranteed to have an odd number of prime factors.
Given ANY number, it is easy to find a polynomial of order 4 that will generate the above four numbers and the selected fifth. The simplest polynomial or order 3 that will generate the above numbers is Un = (-53n3 + 399n2 - 880n + 552)/6 for n = 1, 2, 3, ... and accordingly, the next number is -83.
A prime number is only divisible by itself and the number one. Prime numbers have to be odd (except for the number 2, which is prime). So smaller numbers like 7 are usually pretty easy to determine if they are prime. But the higher the number value gets, the more complicated it is to determine. So people post a list of prime numbers on the internet so you'll know what the prime numbers are.
Prime numbers have only 2 factors which are themselves and one whereas composite numbers have more than 2 factors
Positive integers with more than two factors.
In math, factors are numbers that can be multiplied together to get another number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because these numbers can be multiplied together to give the product 12.
Perfect squares have an odd number of factors. There are 31 perfect squares less than 1000.

Oh, dude, let me break it down for you! Numbers with an odd number of factors are called "square numbers." So, in the range of 1-25, the square numbers are 1, 4, 9, and 25. These numbers have factors like 1, the number itself, and the square root, giving them an odd number of factors. So, like, those are the ones you're looking for!
an easy way to find a factor is... firt you make a chart like this... if your number is 10 then. 10 1x10 2x5 so the prime numbers are 3 and 4 the factors are 1,10,2 and 5. hope this will help :) :) :) :) :) :)

Definition: Prime Number -- the only factors that can go into the number are 1 and itself. Their are simple tricks: numbers that end in 2, 4, 6, 8, 0, and 5 are not prime.My method just makes it easy to know which ones aren't prime.
An easy way to calculate all the factors of whole numbers is to iterate from 1 to that number and check if the remainder is zero using the "%" operation. def getFactors(num): """Return the factors of a whole number""" factors = [] for i in range(1,num+1): if num%i == 0: factors.append(i) return factors Factoring negative numbers and zero simply requires a few more tweaks to the code.
Factors are numbers we can multiply together to get another number: Example: 2 and 3 are factors of 6, because 2 × 3 = 6. A number can have MANY factors!So, an easy way of finding your answers is to look at a timetable charts and analyze what equals to 2,4 and #5.

While there are many ways to determine whether a number is prime or composite, there are easy ways to check numbers up to 100:Try factoring the number. A prime numbers has exactly two factors, 1 and the number itself, and a composite number has one or more factors in addition to 1 and the number itself.All numbers greater than 2 and less than 49 are composites if they are even numbers, if they are multiples of 3, or if they end in 5 or 0.Composite numbers 8 to 100 include the above and all numbers divisible by 7.Test larger numbers by trial division by larger primes that are less than the square root of the number.
