32 x 72 = 441

3 x 3 x 7 x 7 = 441

To find the prime factors of a number, you should start by dividing it by any obvious divisors. In this case, the digit sum of 441 is 9, and so we know that it can divide by 9. Do this and we get 49, which is known from times tables to be 7x7. 9 can be broken down into 3x3. Thus the number 441 can be expressed as 3x3x7x7.

The Prime Factors of 441 are 3, 7

It is a composite number because it has more than two factors.

441 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 9 factors of 441 are 1, 3, 7, 9, 21, 49, 63, 147, and 441. It is a square number (21 x 21), so it has an odd number of factors.The factor pairs of 441 are 1 x 441, 3 x 147, 7 x 63, 9 x 49, and 21 x 21.The proper factors of 441 are 1, 3, 7, 9, 21, 49, 63, and 147 or,if the definition you are using excludes 1, they are 3, 7, 9, 21, 49, 63, and 147.The prime factors of 441 are 3, 3, 7, 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 distinct prime factors of 441 are 3 and 7.The prime factorization of 441 is 3 x 3 x 7 x 7 or, in exponential form, 32 x 72.
