240
Answer: LCM of 30 and 48 is 240.
What is the highest common factor of 30 40 and 48?
As you can see when you list out the factors of each number, 2 is the greatest number that 30, 40, 48, and 30 divides into.
What is the highest common factor of 30?
The prime factors of 30 are 2 x 3 x 5. The prime factors they have in common are 3 x 5. 3 x 5 = 15. The greatest common factor is 15.
What is the highest common factor of 30 and 45?
15
The GCF of 30 and 45 is 15. To calculate the greatest common factor of 30 and 45, we need to factor each number (factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30; factors of 45 = 1, 3, 5, 9, 15, 45) and choose the greatest factor that exactly divides both 30 and 45, i.e., 15.
What is the least common multiples of 48 and 56?
The LCM of 48 and 56 is 336.
How do you calculate the greatest common factor?
To find the greatest common factor (GCF) between numbers, take each number and write it’s prime factorization. Then, identify the factors common to each number and multiply those common factors together.
How do you factor out the GCF?
Factoring out the GCF is the first step in many factoring problems. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.
What is an example of GCF?
For a number, The Greatest Common Factor (GCF) is the largest number that will divided evenly into that number. For example, for 24, the GCF is 12.
What are the factors of GCF?
The GCF of two numbers is the largest factor of the two numbers. For instance, find GCF of 16 and 24 written as GCF (16,24). The factors for 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The largest factor for both numbers have in common is 8, so GCF (16,24) = 8. The factors for 7 are 1 and 7.
