because it can go into every number

The LCF of any pair of numbers is always 1, since it is the lowest number that can be a factor and is a trivial factor of all numbers. The least common factor of any set of numbers is 1.
There are square numbers (numbers which are a square of an integer), such as 4. It's factors, listed are 1, 2, and 4. All square numbers have an odd number of factors. Then there's 1, which has only 1 factor: 1. All other numbers have an even number of factors. Prime numbers will have only 2 factors (2 is even).
As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.
A factor of a number will divide that number evenly. A common factor is any factor which two numbers share. One of the numbers here is 1. The only number that can divide evenly in to is 1. Therefore, it doesn't matter what the other number is, the HCF can only be 1.
Only the number 1 is a factor of all other integers.
1
The number 1.
Possiblilty is almost 1/2 cause every two numbers is a number with a factor of 2.From 2: 2,3,4,5,6,7,8,9,10...
1 is a factor of all positive numbers.
Yes, 1 would be a factor of all numbers because 1 times that nuumber gets you that number.
1
Yes and it is 1.One.
1
A factor of all even numbers is 2.
Yes, all number with have the factor 1 and itself.
