Write the prime factorization using exponents of each number then find the greatest common factor of the numbers 12 and 15?
2.2.3 and
What is the greatest common factor of 2 8 16 and 40?
2 is the greatest common factor because it is the largest factor that divides each number without a remainder.
What is the LCM of 12 6 and 3?
The LCM is 12.
How could you use a Venn Diagram to help find the greatest common factor of two Numbers?
Write the factors of the first number in the left circle. Write the factors of the second number in the right circle. Write the numbers that are the same in each individual circle in the space where they intersect.
When factorising find the common factor?
To find the common factor when factorising, look for any common factors that can be divided evenly from all the terms in the expression. Divide each term by this common factor, and then factorise the resulting expression further if possible. This will help simplify the expression and make it easier to work with.
Write down the highest common factor of 85 and 155?
Prime factor each number and choose the common factors to multiply.85=5x17155=5x315 is the greatest common factor.
What are the steps for greatest common factor?
Step 1 : Prime Factorise each number and write in index notation. Step 2 : Multiply the lowest power of each common factor of the given numbers
How extract common factors from brackets?
You use the distributive property. That is, you look for a common factor, divide each of the terms within parentheses, brackets, or whatever by this common factor, and write the common factor once outside the parentheses. For example: 10x + 15y Here you have a common factor of 5, so you can take this factor out: 10x + 15y = (10x + 15y) = 5(2x + 3y)
What is the greatest common factor of 154 and 70?
Write out all the factors of each , and collect those that are the same in each, and multiply them. Answer 14

Is the greatest common factor how many of each type?
No. The Greatest Common Factor (GCF) is the greatest factor that is in common with the numbers you are given.
What are the common factors and greatest common factor of 74270?
To have a common factor, two or more numbers must be factored and the largest factor that occurs in each number is the greatest common factor.
What is the common factor 15 and 16 have in common with each other?
1
What do the numbers 12 49 and 45 have in common?
Their only common factor is 1. They each have a repeated prime factor.
What is the difference between greatest common factor and least common factor?
The greatest common factor of two (or more) integers is the biggest whole number that divides into each one of them. The least common factor is the smallest whole number that divides into each one of them and must be 1. Very possibly, you meant the least common multiple, however?
Greatest common factor of 30 and 49?
The greatest common factor of 30 and 49 is 1. This is because 30 and 49 are prime to each other;that is, they only have one factor common to both of them. And that factor is 1.
