LCM is 40, which is the multiple of the highest power of prime factors in the given numbers (23 x 5).

To find the smallest number that has 1, 2, 3, 4 and 5 as factors, you're looking for the least common multiple, or LCM, of those numbers. You can find that by listing the multiples of each number but it's faster to combine their prime factors. You need two twos, a three and a five. 2 x 2 x 3 x 5 = 60

The 4 factors of 26 are 1, 2, 13, and 26.The factor pairs of 26 are 1 x 26 and 2 x 13.The proper factors of 26 are 1, 2, and 13 or,if the definition you are using excludes 1, they are 2 and 13.The prime factors of 26 are 2 and 13.The 2 distinct prime factors (listing each prime factor only once) of 26 are 2 and 13.The prime factorization of 26 is 2 x 13.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.

The prime factors of 42 are 2, 3, 1 and 7.The 3 distinct prime factors (listing each prime factor only once) of 42 are also 2, 3, and 7.The prime factorization of 42 is 2 x 3 x 7.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.Factor Tree422, 212, 3, 7Last edit by User: Gracegriffiths.

To find the GCF or the LCM of a set of numbers, it is sometimes practical to write out lists of the factors or multiples as the case may be and compare them. This is known as the listing method.

The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.

Yes. Naming all the common factors is listing each factor that both numbers share. The GCF is the largest number from that list of factors.

Not normally.
