441 = 3 * 3 * 7 * 7
Any number whose digits add up to 9 or a multiple of 9 is divisible by 9. Since the numbers' digits also add up to a multiple of 3, 441 is also divisible by 3.A complete list of all of the positive integer factors of the number is:1, 3, 7, 9, 21, 49, 63, 147, 441441 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
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.
