Let's call G the gcd and L the LCM of two numbers W and A ( for Wiki Answers)
We know LG=WA
and we are told L=90 and G=3So we have LG=270
Now, we are also told W=A+3 So let's substitute,
270=WA=A(A+3)so we have A^2+3A-270=0Now factor this (x-15)(x+18)=0 so x= 15 is one answer and x=15+3=18 is the other number.
Let's check and see if it works.
1. 18=15+3 so that condition is satisfied2. GCD is 3 and the LCM is 90 as desired.So we are done and the answer is:
15 and 18

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.
Can you find the greatest common multiple of two numbers?
The greatest common multiple of any two numbers is infinite.
What is the greatest common multiple of 16 and 56?
The greatest common multiple of any set of numbers is infinite.
What is the greatest common factor of 5p?
There is not a greatest common factor of a single number, such as 5p, because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.The factors of 5p are 1, 5, p, and 5p.Examples:The greatest common factor of 5p and 30p is 5p.The greatest common factor of 5p and 43p is p.The greatest common factor of 5p and 83 is 1, unless p is a multiple of 83, in which case the greatest common factor is 83.
Is great of common factors or more numbers called?
The greatest of common factors of two or more numbers is called the greatest common factor, or GCF.
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 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.
