5 Answers
Explanation:
Factors of
i.e. in all
Explanation:
To find the answer, first factor
144=2×72
=2×2×36
=2×2×2×18
=2×2×2×2×9
=2×2×2×2×3×3
=24×32
Any positive factor of
2a×3b
where
That gives
Since there are only two distinct primes involved, we can write the factors in a grid with columns for the distinct powers of
it has 15 factors ={ 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144}

Explanation:
The most accurate, yet the most complex method is first, prime decomposing and then using the exponent to calculate how many factors a set number
- Prime decompose the number:
=
=
- Add
1 to each exponent:
=
=
- Find the products of the exponents:
=
=
