The factors of 40 are: 1 2 4 5 8 10 20 40 The prime factors are: 2 x 2 x 2 x 5 Answer: 4
420 has four prime factors. Prime factors don't usually travel in pairs.
If pairs of factors separate independently of other pairs of factors, you are dealing with the: Law of independent assortment
Factors go in pairs; prime factors are listed least to greatest. 2, 3 and 11
Factors: 1, 3, 9, 27. Pairs: (1,27);(3,9).
How they're listed. The factors of 20 are 1, 2, 4, 5, 10, 20 The factor pairs of 20 are (20,1)(10,2)(5,4)
40,120,210,48,5
3 pairs
Explaining how to find all factors pairs of 40 is easy. All you have to do is find which whole numbers 40 can be divided into.
40,=1,2,4,5,8,10,20 AND 40
To find the pairs of whole numbers that multiply to equal 40, we can identify the factor pairs of 40. The pairs are (1, 40), (2, 20), (4, 10), and (5, 8). Including the reverse pairs, there are a total of 8 pairs: (1, 40), (40, 1), (2, 20), (20, 2), (4, 10), (10, 4), (5, 8), and (8, 5). Thus, there are 8 pairs of whole numbers that equal 40.
420 has four prime factors. Prime factors don't usually travel in pairs.
Factors for 4 are: 1, 2, 4 It has 2 pairs = 1 * 4 or 2 * 2
There 4 pairs of primes that can give a sum 40 in addition. They are (3,37), (11,29), (17,23),(19,21).
(1, 80); (2, 40); (4, 20); (5, 16); (8, 10).
20 of them
4, if you multiply them.
There are infinitely many pairs. The simplest to find is 1 and 40.
