What is the smallest number with prime factors 2 3 and 7?
The smallest number (positive integer) which has prime factors 2, 3 and 7 is 2*3*7 = 42. A positive integer N has prime factors 2, 3 and 7 if and only if it is a positive integral multiple of 42; i.e. if and only if there exists a positive integer k such that N = 42*k.
How to find all prime factors of a given integer number?
Use this prime numbers calculator to find all prime factors of a given integer number up to 10 trillion. This calculator presents: For the first 5000 prime numbers, this calculator indicates the index of the prime number. The nth prime number is denoted as Prime [n], so Prime [1] = 2, Prime [2] = 3, Prime [3] = 5, and so on.
What is primeprime factorization?
Prime factorization is the decomposition of a composite number into a product of prime numbers. There are many factoring algorithms, some more complicated than others.
What is a prime number?
Prime numbers are natural numbers (positive whole numbers that sometimes include 0 in certain definitions) that are greater than 1, that cannot be formed by multiplying two smaller numbers. An example of a prime number is 7, since it can only be formed by multiplying the numbers 1 and 7. Other examples include 2, 3, 5, 11, etc.
