When a number is a multiple of another the GCF of the numbers is the greatest common factor?
The GCF of the numbers is the greatest common factor no matter what their relationship is. When one number is a multiple of another number, the GCF is the smaller number.
What are the greatest common factor and least common multiple of 3 and 5?
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
What are two numbers with a greatest common factor and a least common multiple of 28?
28 and 28
What is the definition for least common factor?
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. All nonzero numbers have 1 as a factor. The least common factor of any set of positive integers is 1.
What is the greatest common multiple of 32and 55?
The greatest common multiple of any set of positive numbers is infinity.I suspect you actually want to know the greatest common factor and not multiple.The greatest common factor is 1.
Name numbers that least common multiple is the same as its factor?
All numbers with a least common multiple, have that multiple as a factor.
How can you express (15 plus 30) as a multiple of a sum of whole numbers with no common factor?
It is 15*(1 + 2)
Is the least common multiple of two numbers always divisible by the greatest common factor of the two numbers?
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
Is 12 a common factor of 3 and 4?
No, it is not a factor of either of the numbers.
What is the lowest common multiple of 30 and the greatest common factor of 3?
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.
WhoNiamh thinks of two numbers.The highest common factor of the two numbers is 8.The lowest common multiple of the two numbers is a multiple of 5.What are the two numbers?
Well, isn't that just a happy little math problem we have here! Let's see, if the highest common factor is 8, then the two numbers must both be multiples of 8. And if the lowest common multiple is a multiple of 5, then the two numbers must also be multiples of 5. So, the two numbers Niamh is thinking of are 40 and 80. Happy calculating!
How do you know whether to use the greatest common factor or the least common multiple to solve a problem?
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
Does a factor mean the same as a highest common multiple?
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.
What is the least common multiple of 32 and 15?
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.
What is the least common factor of two numbers when one number is a multiple of the other?
The least common factor of any set of numbers is 1.
What is the difference between a common multiple and a common factor?
Factors go into numbers, numbers go into multiples.
When the greatest common factor is 1 is the least common multiple of these numbers always the product of the numbers?
Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.
