What are the factors and prime factors of -200?

Answer 1

-200 is a composite number because it has factors other than 1 and itself. It is not a Prime number. No negative number can be a prime number.

The 24 factors of -200 are ±1, ±2, ±4, ±5, ±8, ±10, ±20, ±25, ±40, ±50, ±100, ±200.

The prime factors of -200 are -1, 2, 2, 2, 5, and 5. Technically, -1 is not a prime factor (it is a unitary factor), but it is included here because the number is negative. 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.

The 2 distinct prime factors (listing each prime factor only once) of -200 are 2 and 5.

The prime factorization of -200 is -1 x 2 x 2 x 2 x 5 x 5 or, in index form (in other words, using exponents), -1 x 23 x 52.

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.
