Well, isn't that a happy little question! Let's take a look at 840. Its factors are numbers that can be multiplied together to give 840, like 1, 2, 3, 4, and so on. The prime factors are the factors that are also prime numbers, like 2, 3, 5, and 7. Just like painting a beautiful landscape, understanding factors can help us see the beauty in numbers!

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

The 32 factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, and 840.

The proper factors of 840 are 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, and 420 or,

if the definition you are using excludes 1, they are 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, and 420.

The prime factors of 840 are 2, 2, 2, 3, 5, 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.

The 4 distinct prime factors (listing each prime factor only once) of 840 are 2, 3, 5, and 7.

The prime factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7 or, in index form (in other words, using exponents), 23 x 3 x 5 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.
