What are the factors of -126?

Answer 1

-126 is a composite number because it has factors other than 1 and itself. It is not a Prime number. Negative numbers are not prime numbers

The 24 factors of -126 are ±1, ±2, ±3, ±6, ±7, ±9, ±14, ±18, ±21, ±42, ±63, and ±126.

The factor pairs of -126 are -1 x 126, -2 x 63, -3 x 42, -6 x 21, -7 x 18, -9 x 14, 1 x -126, 2 x -63, 3 x -42, 6 x -21, 7 x -18, and 9 x -14.

The proper factors of -126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63 or,

if the definition you are using excludes 1, they are 2, 3, 6, 7, 9, 14, 18, 21, 42, and 63.

Note: Proper factors usually include only positive factors.

The prime factors of -126 are -1, 2, 3, 3, and 7.

Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed. Also, -1 is not a prime factor, but it is included to show that the number is negative.

The distinct prime factors (listing each prime factor only once) of -126 are -1, 2, 3, and 7.

Note: The -1 is not always listed in the list of distinct prime factors.

The prime factorization of -126 is -1 x 2 x 3 x 3 x 7 or, in exponential form, -1 x 2 x 32 x 7.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
