Because 1, 6, 2, and 3 can all be multiplied by a whole number and equal 6
Its factors are: 1 2 3 and 6
No, there are four.
Sure. Take any positive number and find its factors. Then, if you make an odd number of the factors negative, you then have a set of factors of the negative of the original composite number. That means that the factors of a negative number are not 'unique'. Take ' 6 ' for example. Its factors are 1, 2, 3, and 6. If you make the '1' or the '2' or the '3' or the '6' negative, then you have four factors of ' -6 '. Are there any other ways to make an odd number of them negative ? I see eight different ways to make an odd number of those four numbers negative. So ' -6 ' has eight different possible sets of factors. Is that weird or what !
6, 8 and 10 are some numbers with four factors.
Four factors in common.
6 is.
6
Ah, let's take a moment to appreciate the number 6. It has four factors: 1, 2, 3, and 6. Each of these numbers can be multiplied together to give us 6. Isn't that just lovely?
21 has four factors: 1, 3, 7 and 21.
3, 5 and 6 are factors of 30
1,2,3,6.So, it has four.
6: 1, 2, 3, 6
