To find a pair of numbers with a given GCF, take the GCF number and double it. The pair of numbers is the GCF, and two times the GCF. For instance, two numbers with a GCF of 3 are 3 and 6.
3 and 6
You need at least two numbers to find a GCF.
When you are trying to find the GCF of two numbers and one of the numbers is a multiple of the other, the GCF will be the smaller of the two numbers. The GCF of 3 and 9 is 3.
The same as what? The GCF of two numbers will be the same; the GCF of 3 and 9 will always be 3. The GCF of 9 and 12 will also always be 3, but the GCF of 4 and 12 will always be 4.
In math the GCF of the numbers 3 and 63 is three. In mathematics the GCF is the greatest common factor of two or more numbers. The GCF can be found by listing the prime numbers for each number and then multiplying the common prime numbers.
3 and 12
3 and 36
3 and 84
The product of the GCF and the LCM is the same as the product of the original two numbers. Divide the product of the original numbers by the GCF. The result will be the LCM.
You need at least two numbers to find a GCF. If that's 6 and 15, the GCF is 3.
You need at least two numbers to find a GCF. If that's 15 and 12, the GCF is 3.
