Example:Find the GCF of 20 and 25. Factors of 20: 1, 2, 4, 5, 10, and 20. Factors of 25: 1, 5 and 25. Common factors: 1 and 5. Greatest Common Factor (GCF) = 5. This method can be used for finding GCF of three or more numbers as well. ...
GCF of 40 and 72 is the largest possible number which divides 40 and 72 without leaving any remainder. The methods to compute the GCF of 40, 72 are explained here.
GCF of 28 and 40 is the largest possible number which divides 28 and 40 without leaving any remainder. The methods to compute the GCF of 28, 40 are explained here.
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4....
The greatest common factor or GCF is the largest value number that is a factor of two or more numbers. Using the same example as before, the greatest common factor between 8, 12, and 24 would be 4, because 4 is the largest factor that the three numbers have in common. How...

Knowing that, let's estimate the greatest common denominator of numbers 72 and 40. Factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72. Factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40. List all the common factors: 1, 2, 4, 8. The Greatest Common Divisor...
The numbers are 3 and 4. x2+7 x+12=(x+3) (x+4) EXAMPLE 2 Factor. x2+12 x+20 We want two numbers that have a product of 20 but a sum of 12. The numbers are 10 and 2. x2+12 x+20=(x+10) (...
Factors of 100: 1, 2, 4, 5, 10, 20, 25, 50, 100 When you compare the two lists of factors, you can see that the only common factor is 1. So, in this case, the GCF of 27 and 100 is 1. Find the GCF of Other Number Pairs Want more practice? Try some of these other GCF...
Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, … The common multiples have been encircled below: The common multiples of 4 and 5 are 20, 40, and so on. The least of these common multiples is 20. Hence the LCM of 4 and 5 is 20. Example 4: Sam write...
