In math it means Greatest Common Factor. Any two or more numbers will have some factors, or divisors, in common.. The largest of these common factors is the GCF. For example.
Take 12 and 14
The factors of 12 are 1,2,3,4,6,and 12 and of 14 they are 1,2,7,and 14.
The common factors are 1 and 2 and 2 is the greatest so it is the GCF. GCF stands for greatest common factor == A GCF exactly is called greatest common factor. For example: the factors of 8 and 18 are 8== 1,2,4,8; 18=1,2,3,6,9,18. So you look at the factors of both numbers and the greatest one is 2. So the GCF of 8 and 18 is 2. [: Hope this helps :] ===
Greatest common factor.
GCF doesn't apply to fractions, only to whole numbers. When those numbers are the numerator and denominator of a fraction, the GCF can be used to reduce it to its simplest form.
LCD:Lowest Common Denominator GCF:Greatest Common Factor
Find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is in its lowest terms, also known as simplest form.
By GCF you mean Greatest Common Divisor = 72
The GCF for 16 24 18 is 2.
If you mean 18, 27 and 63 then the GCF is 9
If you mean 300 and 450 then the GCF is 150
If you mean 45 and 18 then the gcf is 9
If you mean 40 and 80 then the GCF is 40
If you mean: 18, 36 and 45 then the GCF is 9
If you mean 18, 36 and 45 then the gcf is 9
If you mean 55, 77 and 143 then the GCF is 11
If you mean 18, 27 and 63 then the GCF is 9
If you mean 25, 100 and 50 then the GCF is 25
If you mean: 15, 30 and 45 then the GCF is 15
If you mean 15, 45 and 75 then the GCF is 15
The GCF is 27.
