What is the gcf of 53 and 86 using prime factorization?
53 is already prime. 2 x 43 = 86 No common prime factors; the GCF is 1.
What is the GCF and LCM of 12 and 27 using prime factorization?
2 x 2 x 3 = 12 3 x 3 x 3 = 27 The GCF is 3. The LCM is 2 x 2 x 3 x 3 x 3, or 108
What is the division ladder of 10?
The prime factorization of 10 is 2 x 5. You need another number to find a GCF or LCM.
What is the least common multiple of 25 and 30?
The LCM of 25 and 30 is: 150The prime factorization of 25 = 5x5The prime factorization of 30 = 2x3x5GCF = 5But, what is the use of calculating GCF here?Answer: If we divide the product of 25 and 30 by GCF then the result is LCM.Product of 25 & 30 = 25x30 = 750So, LCM = 750/5 =150Least Common Multiple (LCM) for 25 30 is 150
What is the prime factorization of both the numerator and the denominator of the fraction?
Take 30/42, for example. The prime factorization of the numerator (30) is 2 x 3 x 5. The prime factorization of the denominator (42) is 2 x 3 x 7. This will help you find the GCF or the LCM.
What is the gcf and LCM of 60 72 using prime factorization?
They are: 12 and 360 respectively
What do you use prime factorization for?
To answer GCF and LCM questions.
How are gcf LCM and prime factorization related?
You can find the GCF and/or the LCM of a set of numbers by comparing the prime factorizations of the individual members of the set.
What is the LCM and gcf of 18 and 360?
Product of two numbers a and b = LCM(a,b) x GCF(a,b)...(1)Here, product of 18 and 360 = 6480Now, we shall find GCF of 18 and 360 by using the method of prime factorization.Prime factorization of 18 = 2x3x3Prime factorization of 360 = 2x2x2x3x3x5It is clear from the prime factorization that gcf = 18Now using (1) we can find LCM:LCM(18,360) = Product of 18 and 360/GCF(18,360) = 6480/18 = 360So, LCM and GCF of 18 & 360 is 360 and 18.Also, it is important to note that 360 is divisible by 18 then GCF is 18 and LCM is 360.
What is the definition and purpose of prime factorization?
Prime factorization is the result of expressing a number as the product of its prime factors. It will assist you in finding the GCF and LCM of any given number set.
