The multiplicity of a prime factor p of n is the largest exponent m for which p m divides n. The tables show the multiplicity for each prime factor. ... 63: 3 2 ·7 ...
63 is a Mersenne number of the form with an of , [5] however this does not yield a Mersenne prime, as 63 is the forty-fourth composite number. [6] It is the only number in the Mersenne sequence whose prime factors are each factors of at least one previous element of the sequence ( 3 and 7 , respectively the first and second Mersenne primes). [ 7 ]
Every positive integer greater than 1 is either the product of two or more integer factors greater than 1, in which case it is called a composite number, or it is not, in which case it is called a prime number. For example, 15 is a composite number because 15 = 3 · 5, but 7 is a prime number because it cannot be decomposed in this way.

The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science. As a journal-level metric, it is frequently used as a proxy for ...
Proof: By Fermat's little theorem, q is a factor of 2 q−1 − 1. Since q is a factor of 2 p − 1, for all positive integers c, q is also a factor of 2 pc − 1. Since p is prime and q is not a factor of 2 1 − 1, p is also the smallest positive integer x such that q is a factor of 2 x − 1.
Divisor. In mathematics, a divisor of an integer also called a factor of is an integer that may be multiplied by some integer to produce [1] In this case, one also says that is a multiple of An integer is divisible or evenly divisible by another integer if is a divisor of ; this implies dividing by leaves no remainder.
where is the th successive prime number, and all omitted terms (a 22 to a 228) are factors with exponent equal to one (i.e. the number is ). More concisely, it is the product of seven distinct primorials:
