One is a factor of every number.
yes it is a factor for every number.
Every number has one as a factor because one can divide into any number with no remainder. Every number does not have one as a proper factor because the set of proper factors does not contain one and the number itself.
The greatest factor of any number is the number itself. There is no integer that is the greatest factor of every number. One is a factor of every number. One is the GCF of co-prime numbers.
One is the only number that is a factor of every other number.
It's part of the identity property. Pick a number. Multiply it by one. The answer will be the number. That means that every number has the factor pair of itself and 1, so every number has one as a common factor.
If there is no factor that both of the numbers share (and there is not because they are both prime), then the answer is one. Every number has a factor of one, because every number times one is itself.
The common factor of every set of numbers is 1 because one is a factor of every number.
2 is a factor of every even number. Adding or subtracting one from an even number leaves an odd number. Since even and odd numbers alternate, 2 will be a factor of every other number.
1 is a factor of every number.1 is a factor of every number.
The number one is a factor of every number.
Because every number can be divided by one with no remainder.
The number one.
One and two.
The factor is 1.
No because you have to have a prime number besides 1 like 2,5,7 because every time you use a factor tree and you put a 1 as prime you keep getting one every time.So one can not be use as a factor when doing a factor tree.
1 is a factor of every number.
Because one is a common factor of every number.
