To make sure your fraction is in its lowest terms, find the GCF of the numerator and the denominator. If the GCF is 1, the fraction is in its lowest terms. If the GCF is greater than 1, divide both the numerator and the denominator by the GCF to reduce the fraction.Example: 30/42The GCF of 30 and 42 is 66 into 30 is 5, 6 into 42 is 730/42 = 5/7
Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 20: 1, 2, 4, 5, 10, 20 Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24 GCF (12, 20, 24) = 4
The GCF is 2.
6*4/5 = 24/5 = 44/5 or 4.8
To divide a fraction by a fraction, multiply the first fraction by the reciprocal of the second. To reduce a fraction to its simplest form, find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form. 4/5 divided by 3/6 = 4/5 x 6/3 = 24/15 = 8/5
The GCF is 1.
The GCF is 1.
The GCF is 1.
The GCF of 2, 4, 5, and 6 is 1.
You need at least two numbers to find a GCF. If that's 4, 5 and 6, the GCF is 1.
There can be only one GCF, not a pair. GCF(4, 6) = 2
The factors of 5 are:1, 5The factors of 6 are:1, 2, 3, 6The factors of 12 are:1, 2, 3, 4, 6, 12The Greatest Common Factor (GCF) is:1
1, 2, 3, 4, 6, 121, 2, 4, 5, 10, 20The GCF is 4.
The GCF is 1.
The GCF is 1.
The GCF of 4, 6, and 8 is 2. 1. Take the smallest number. 2. Note its factors. 3. Starting with the largest, ask if this factor is also a factor of the other numbers. 4. If it is you have found the gcf. 5. If it is not take the next largest factor. Repeat steps 3 to 5 until you have found the gcf. So here: Take 4.2. The factors of 4 are 1,2 & 4.3. Is 4 a factor of 6 and 8? No it is not a factor of 6.4. The next largest is 2. Is it a factor of 6 and 8? Yes. The gcf is therefore 2. The GCF is 2. The GCF is 2.
