The greatest common factor is exactly as it sounds: the greatest
factors of two or more numbers.
Find the common factors for 60 and 30
Begin by factoring both numbers. Find all factors that the
numbers have in common.
The product of all common factors is the greatest common factor
The greatest common factor is 30
You can also determine the GCF if you have both numbers and
Find the common factors for 36x2y and 16xy
Factorize the numbers and identify all common factors. To get
the GCF multiply all common factors.
You can use the greatest common factor to simplify
A ratio is an expression that tells us the quotient of two
There are different ways to write a ratio and all examples below
are read as "the ratio of 3 to 4".
You can simplify a ratio by findng the GCF
Fraction all numbers and find all common factors
Multiply all common factors to find the GCF
Since the GCF is a factor of both the numerator and the
denominator we can divide both the numerator and the denominator by
the GCF to produce a simplified fraction.
