what is a factor string with 1 to 144
It's a pretty short string. 29 is prime, its only factors are 1 and itself.
The proper factor of 21 is 1, 3 and 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.
1*2*2*2*3*3*5=360
what is a factor string with 1 to 144
Depending on your definition of proper factors, the set of proper factor factors either doesn't include 1 and/or the number itself for a given number.
If you include 1 as a proper factor, the answer is 64.
A factor string is a name for a number written as a product of two or more factors. In a factor string, 1 may not be used as a factor. For example, a factor string for 24 is 2 X 3 X 4, or 2 3 4.:0
Actually, 25 is NOT a proper factor of 25. Factors are numbers that, when multiplied with another factor, result in the number, like 25. Proper factors are just like regular factors EXCEPT they do not include the actual number. The proper factors of 25 are 1 and 5.
No.
4 3 and 6 have no proper factor in common. Remember that 1 is a factor of every counting number, but not a proper factor of any of them. Greatest common factor questions do not recognise 1 as a proper factor. When talking of primes neither 1 nor the number itself is regarded as a proper factor.
One has no proper factors.
No.
Good question. The short answer is "No," but there is some disagreement. Some people include 1, others do not. Part of the trouble comes from some countries that use the term "factor," others that use the term "divisor," and others which use them interchangeably. If I ruled the world, or even the math portion of it, here's what I would decree: A proper factor of a positive integer N is a factor of N other than 1 or N. For example, 2 and 3 are positive proper factors of 6, but 1 and 6 are not. Compare with the term proper divisor, which means a factor of N other than N (but including 1).
It's a pretty short string. 29 is prime, its only factors are 1 and itself.
The proper factors of 99 are: 1, 3, 9, 11, 33. A proper factor is any factor of the number that is not itself.
