This is exactly φ(21600) where φ is the Euler totient function. φ(21600) = 5760 That is, there are 5760 such numbers between 1 and 21600.
There is no common factor for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
If we are trying to find the two numbers less than 50 with the greatest common factor, we need to pick two numbers with a larger difference between them, since the greatest common factor between two numbers cannot be greatest than the difference between the two numbers. To create a large difference, we will want one number to be close in value to 50. And, for the greatest common factor, we want the other number itself to be the greatest common factor. The greatest common factor that the larger number can have (since it is larger and thus cannot be the greatest common factor itself) is the number which is half its value. So, if we choose the even number closest in value to 50, we get 48. Then, if we take half of it, we get 24. The greatest common factor of 24 and 48 is 24. This is the largest possible greatest common factor of a pair of numbers less than 50.
Answer: None, it is impossible. No single number has a greatest common factor. A "common factor" is a factor that two or more numbers have in common. The "greatest common factor" is the largest factor that two or more numbers have in common.
A factor is any number, normally an integer, that multiplies by another number or set of numbers to produce the number of which it is a factor. Eg. the factors of 32 are 1,2,4,8,16 and 32. A common factor is a factor that is shared by two numbers, and is commonly use in conjunction with the term "highest common factor", which demands the highest possible shared factor of two numbers. Eg. the common factors of 14 and 21 are 7 and 1.
what two numbers between 50 and 60 are both multiples of the same number. what factor do they have in common?
It has none - you can only have a common factor between two or more numbers.
The greatest common factor of 99 and 25 is 1. There are not other numbers that are common between them.
There cannot be a common factor of just one number. To be common there need to be at least two numbers.
There is no common factor for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
There is no such thing as the common factor of a single number. Only two or more numbers can have a common factor. This is like asking what is common between me and myself. Everything. But you could ask what is common between you and your sister.
1 is the factor that is common to all numbers.

A number that is a factor of two or more numbers is simply a common factor
A factor is any number, normally an integer, that multiplies by another number or set of numbers to produce the number of which it is a factor. Eg. the factors of 32 are 1,2,4,8,16 and 32. A common factor is a factor that is shared by two numbers, and is commonly use in conjunction with the term "highest common factor", which demands the highest possible shared factor of two numbers. Eg. the common factors of 14 and 21 are 7 and 1.
There can only be a "common" factor between two or more numbers. You have listed only one number. The highest factor of 172,000 is 172,000.
You need at least two numbers to find a GCF. You probably have that here but without spaces between the numbers, we don't know what they are.
