Yes, just as 1 is considered a factor of everything, a number is considered a factor of itself.
1 is not considered to be a prime or composite number because it has only one factor which is itself.
If the number 1 is considered a factor, then these are the prime numbers. Their only factors are 1 and themselves.
No. Apart from -1 and 1, no other whole number is a factor of 1.
It is. 1 is a factor of every whole number.
Yes, just as 1 is considered a factor of everything, a number is considered a factor of itself.
If 1 is considered a factor, the only common factor of 21 & 19 is 1, because 19 is a prime number. I'm not sure whether 1 is considered a factor since it does not reduce the original number and it's not a prime number.
A factor is any number which the original number can divide into evenly. A common factor is a number which is a factor of both numbers being considered. In this case, we have 1. The only nunmber 1 can divide evenly into is 1, and thus this is the only common factor between it and 7. Therefore, the GCF of 1 and 7 is 1.
1 is not considered to be a prime or composite number because it has only one factor which is itself.
1 is a factor of every number.1 is a factor of every number.
If the number 1 is considered a factor, then these are the prime numbers. Their only factors are 1 and themselves.
Every whole number has at least one prime factor.With the possible exception of ' 1 ', whose only factor is ' 1 ' andisn't considered a prime number.
No, 1 is a factor of every whole number because 1 is a factor of every whole number.
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
Yes 1 is a factor of every number except 0. This is literally true but incomplete. The number 1 is a factor of any number and can be that factor an infinite number of times. Most people don't like infinity. It causes many problems. That's (partially) why 1 is not considered a prime number although it has no factors other than itself and 1 (yes, redundant to infinity). So when someone asks for prime factors of a number, be sure to not include 1. Unless you are an infinite entity and infinite time to write out the prime factors.
1 is a factor of every number.
No. But 1 is a factor of 8 Note: A larger number cannot be a factor of a smaller number.
