All numbers with a least common multiple, have that multiple as a factor.

It is 15*(1 + 2)

No, it is not a factor of either of the numbers.

Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.

There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.

A common factor: 1. A common multiple: 30.

Their product.

Factors go into numbers, numbers go into multiples.

Do you mean lowest common multiple? If so it is the smallest multiple that the two numbers have in common

The least common factor of any set of numbers is 1.

Identify two numbers whose Greatest Common Factor is 24 and Least Common Multiple is 48?The two numbers are 12 and 24.

Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.

the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor

12 and 72

No.When talking about factors and multiples the numbers are integers (whole numbers).A factor of a number means that the number is a multiple of the factor; the factor divides into the number without any remainder.There is no such thing as a Highest Common Multiple - it is always possible to find a higher common multiple (by adding the Lowest Common Multiple to the supposed highest common multiple).There is a Lowest Common Multiple (LCM) which is the smallest number which is a multiple of two or more numbers. It is also called the Least Common Multiple, or when working with fractions it can be referred to as the Least Common Denominator as the two or more numbers are the denominators of the fractions and equivalent fractions are being sought to be able to do an addition or subtraction.There is a Highest Common Factor (HCF) which is the largest number which divides into each of the two or more numbers without remainder. It is also called the Greatest Common Factor. If the numbers are relatively prime (or co-prime) their HCF is 1.

No, the GCF is the lesser of the numbers.

If they don't both divide by 3 then no multiple of 3 can be a common factor...

When it is a factor of the larger number for example the least common multiple of 15 and 60 is 60 because 15 is a factor of 60 and 60 is factor of itself

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

The LCM of the two numbers will be their product.

Since 70 is a multiple of 14, it is the least common multiple. Or, you can determine it as you would any pair of numbers. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 14 and 70 is 14. Therefore, the least common multiple 14 x 70 ÷ 14 = 70.

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 28 and 48 is 4. Therefore, the least common multiple is 28 x 48 ÷ 4 = 336.

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 15 and 32 is 1, so the least common multiple is 15 x 32 ÷ 1 = 480.

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 7 and 159 is 1, so the least common multiple is 7 x 159 ÷ 1 = 1113.

The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.
