Did you use the factors of 100 to find the factors 200 if so how?

The prime factors of 100 are 2 x 2 x 5 x 5, and one more x 2 gives the prime factors of 200, 2 x 2 x 2 x 5 x 5. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. These are also the common factors of 100 and 200, but there is no obvious way to find the factors of 200 by using common factors. The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.

What are the factors and prime factors of -200?

-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.
