What are the factors and prime factors of 160?

Answer 1

160 is a composite number because it has factors other than 1 and itself. It is not a Prime number.

The 12 factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160.

The factor pairs of 160 are 1 x 160, 2 x 80, 4 x 40, 5 x 32, 8 x 20, and 10 x 16.

The proper factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, and 80 or,

if the definition you are using excludes 1, they are 2, 4, 5, 8, 10, 16, 20, 32, 40, and 80.

The prime factors of 160 are 2, 2, 2, 2, 2, and 5.

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 160 are 2 and 5.

The prime factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5 or, in index form (in other words, using exponents), 25 x 5.

NOTE: There cannot be common factors, a greatest common factor, or a least common multiple of a single number because "common" refers to factors or multiples that two or more numbers have in common.
As a product of its prime factors in exponents: 2^5 times 5 = 160
2^5 * 5
2 and 5.
