343 = 73

The factors of 343 are thus 1,7,49 and 343.

No combination of two factors adds up to 21, but you could state that 3 factors (7, 7 and 7) total 21.

1029 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 1029 are 1, 3, 7, 21, 49, 147, 343, and 1029.The factor pairs of 1029 are 1 x 1029, 3 x 343, 7 x 147, and 21 x 49.The proper factors of 1029 are 1, 3, 7, 21, 49, 147, and 343 or,if the definition you are using excludes 1, they are 3, 7, 21, 49, 147, and 343.The prime factors of 1029 are 3, 7, 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 2 distinct prime factors (listing each prime factor only once) of 1029 are 3 and 7.The prime factorization of 1029 is 3 x 7 x 7 x 7 or, in index form (in other words, using exponents), 3 x 73.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.

A composite number is a number that has more than two factors. The factors of 21 are 1, 3, 7, and 21. Therefore, 21 is a composite number.

Although negative numbers aren't usually considered factors, you can use -21, -3 and -2.

1, 3, 7, 21, 49, 147, 343, 1029

The factors of 21 that add up to 8 are 1 and 7.

If you mean what numbers add to 10, whose product is 21, that would be 3 and 7.

When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.

Well, 18 and 3 (both factors of 36) add up to 21. As well, the factors 12 and 9 add up to 21.

I think that you meant factors, not fractions. If you meant factors, then it would be 7 and 3. If you did mean fractions, then it would be 0/21 and 210/21.

18 and 3 are factors of 162.
