What pair of numbers has a least common multiple of 20 and a greatest common factor of 2?

If a set of numbers has a lowest multiple of 20, they can't have a highest multiple of 2. The greatest common multiple of any set of numbers is infinite, anyhow, so it's clear that there's a typo in your question.
However, the numbers 4 and 10 have a greatest common factor of 2 and a least common multiple of 20. Perhaps that's what you mean to ask.

∙ 12y agoHCF of 2 means both numbers have a 2 as prime factor, but this is the only common prime factor. LCM of 20, means that between the two numbers we have factors of 2, 2 and 5.
Assuming neither of the numbers are 2 or 20, this means we have to combine one number with the 2 and the other with the 5. This gives us 2x2 and 2x5 or 4 and 10.

∙ 8y ago4 and 10 have an LCM of 20 and a GCF of 2. So do 2 and 20.

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.
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 greatest common multiple of 12 and 18?
There is no such thing as the Greatest Common Multiple. For any multiple calculated, you could add the LCM to get a higher number; essentially, the greatest common multiple of any set of numbers is infinite. The least common multiple of 12 and 18 is 36, The greatest comon factor of 12 and 18 is 6.
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.
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
What is the greatest common multiple between 12 and 15?
There is no "greatest common multiple" for any pair of numbers. If you meant greatest common factor, the answer is 3.
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.
What is the greatest of the common factors of two or more numbers called?
The greatest common factor between two numbers. There is no term.
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 is the greatest common multiple of 36 and 54?
The greatest common multiple of any set of integers is infinite.
What is the least common multiple of 5 and 23?
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 5 and 23 is 1. (See related question "What is the greatest common factor of 5 and 23?" for this calculation.) So, the least common multiple is 5 x 23 ÷ 1 = 115.
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 is the least common multiple of 28 and 48?
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.
What is the least common multiple of 7 and 159?
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.
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.
