7 is a prime number .There are no factors for it.
Aside from itself and 1, the highest factor of 14 is 7.
No, 294 is not a proper factor of 147. Proper factors are smaller than the number of which they are a factor. The proper factors of 147 are 3, 7, 21, 49, and perhaps 1, depending on the definition you are using.
The proper factors of 35 are 5 and 7
5 and 7
The concept of a factor makes proper sense only in the context of integers. Otherwise, any non-zero number can be factor of any other number. For example, radical 7 is a factor of radical 18 since radical(180) = radical(7) * radical (18/7)
The proper factor of 21 is 1, 3 and 7
The proper factors of 147 are 3, 7, 21, and 49
all perfect cubes (any number powered by 3) by adding or subtracting 1 become factor of 7 except base number as 7 and its factors.
The only number that could be both a factor and a multiple is 7 itself.
1, 5, 7 and 35 are the factors of 35. The proper factors are 5 and 7.
The only proper factors of 77 are 7 and 11. 11 isn't a factor of 259 but 7 is, so the answer is 7.
