Example: 30 and 42
1,2,3,5,6,10,15,30
1,2,3,6,7,14,21,42
The GCF is 6.
To find the smallest number that has 1, 2, 3, 4 and 5 as factors, you're looking for the least common multiple, or LCM, of those numbers. You can find that by listing the multiples of each number but it's faster to combine their prime factors. You need two twos, a three and a five. 2 x 2 x 3 x 5 = 60
To find the prime factors of a number, divide the number by each prime number up to the greatest prime that will go into the number leaving no remainder. This is the process for factorization of 168: 168/2=84 84/2=42 42/2=21 21/3=7 7/7=1 Listing each divisor as a prime factor, the prime factors of 324 iare 2x2x2x3x7.
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.
The factors of 1757051 are: 1, 1291, 1361, 1757051
1, 2, 4 Method(s) used: # The method is to find all of the factors of each, and then select the numbers that appear in each list. # Another method to find the common factors of numbers is to find the prime factorizations of each one, select all matching prime factors, and then combine them.
You can start by listing out each number's factors. Then, when you find at least one common factor, that is your answer!

The division ladder is a method used to find the greatest common factor (GCF) of two numbers by listing the factors of each number. To find the GCF of 82, you would start by factoring the number 82. The factors of 82 are 1, 2, 41, and 82. Therefore, the GCF of 82 is 1.
it is easier to find the prime factorization because you do not have to keep multiplying over and over and over again!!!!
Factors of 77: 1, 7, 11, and 77.
Two methods to solve a greatest common factor (GCF) problem are the prime factorization method and the listing method. In the prime factorization method, you find the prime factors of each number and determine the common factors. The GCF is the product of the common prime factors. In the listing method, you list the factors of each number and find the common factors. The GCF is the greatest common factor from the common factors list.

Sure, just tell me what the numbers are.
The greatest common factor (GCF) is the largest factor that two or more numbers have in common. You find the GCF by listing the prime factors of each number. Find the prime factors the numbers have in common and multiply them.154: 2 x 7 x 1142: 2 x 3 x 7The factors they have in common are: 2 x 7GCF = 14
You can quickly find the factors for even numbers 50 to 100 by dividing each number by all possible factors (starting from 2) until reaching the square root of the number. If a number is divisible without a remainder, then it is a factor of that even number. Repeat this process for each even number between 50 and 100.
Please don't use such offensive language.~RH3~The GCF is 2, the LCM is 684.The GCF you can find by listing all the factors of each number-36.......381..........12............23...........194............3269121836Now you want to find the highest possible number on each side (they don't have to lign up). That number is 2. That's your GCF.LCM is listing all the multiples.36......3872.......76108.....152144.....190180.....228216.....266.....Eventually you get to648.....684684......722...............Those are the first number that they both have in common, therefore it's your answer.Hope I helped! Give me trust!~RH3~
-- List all factors of the first number. -- List all factors of the second number. -- If there are more than two numbers, list all factors of each one. -- Find the set of factors that are on every list. -- Find the greatest factor in the set.
