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.
HCF 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.
4 and 10 have an LCM of 20 and a GCF of 2. So do 2 and 20.
You need at least two numbers to find the GCF or LCM.
2 and 24
4 and 6
2 and 4
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.
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.
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
28 and 28
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.
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
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
There is no "greatest common multiple" for any pair of numbers. If you meant greatest common factor, the answer is 3.
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.
The greatest common factor between two numbers. There is no term.
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.
The greatest common multiple of any set of integers is infinite.
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.
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
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 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 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.
