there is no lcf between the two numbers

The LCF of any set of numbers is 1.

If, by LCF you mean Least Common Factor, I regret to inform you that the question makes no sense. Common requires you to have two or more numbers; you cannot have a common factor of just one number. Furthermore, the LCF of any set of numbers is always going to be 1. So it is hardly worth asking the question.

The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common factor of any set of numbers is 1.

You need at least two numbers to find something in common, but the LCF of any set of numbers is 1.

150.

The LCF (Lowest Common Factor - the lowest number that divides both) is 1.I guess you mean either:The HCF (Highest Common Factor - the largest number that divides both) is 18;The LCM (Lowest Common Multiple - the smallest number they both divide) is 252.The HCF is also called the GCF - Greatest Common Factor.

The LCF of any two numbers is always 1.

You need to have at least two numbers to find an LCF, but I'll save you the trouble. The LCF of any two numbers is one. It's usually more productive to find the GCF or the LCM.

The LCF (least common factor) of any two numbers is 1.

The GCF is 2. The LCF is 1.

The LCF, or least common factor,of any two or more numbers will always be 1.

Since the CFs of neither match, you have to multiply the two numbers together. The answer you get is the LCF. You do the math.

The LCF (Lowest Common Factor) of any two numbers is 1 (as 1 is a factor of all numbers).However, I suspect you mean LCM - Lowest Common Multiple.Write the numbers in their prime factorisations in power form. Then for the HCF use the lowest power of each prime across all the numbers (if a prime does not appear in the factorization of a number, its power is zero) and for the LCM use the highest power of each prime across all the numbers:192: 26 x 3224: 25 x 7HCF: 25 x 30 x 70 = 32 x 1 x 1 = 32LCM: 26 x 31 x 71 = 64 x 3 x 7 = 1344

The GCF is 34. The least common factor of any set of integers is 1.

The LCf of any two nonzero whole numbers is one because every nonzero whole number can be divided by it.

You cannot find the lowest common factor of a single number - lowest common factor is used as a comparison of two or more numbers.

you can't have an LCF of one number... you need at least 2 numbers, it is called COMMON, isn't it?

This question mixes up two different concepts - that of the highest common factor (HCF) and lowest common multiple (LCM).

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.
