What is the least common multiple of 5.9 and 15?

45
LCM of 5, 9, and 15 by Prime Factorization LCM of 5, 9, and 15 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 32 × 51 = 45. Hence, the LCM of 5, 9, and 15 by prime factorization is 45.

### How do you find the L.C.M. and HCF of a polynomial?

The relation between L.C.M and H.C.F of polynomials is the product of polynomials is equal to the product of its H.C.F and L.C.M. This relationship can be expressed as follows. p(x) * q(x) = {L.C.M of p(x) and q(x)} * {H.C.F of p(x) and q(x)]}.

HOW TO FIND GCD AND LCM OF TWO POLYNOMIALS

1. The coefficients of the variables like x as much as possible.
2. If there is quadratic or cubic polynomial, then it has to be factored suitable algebraic identities.
3. To find GCD, multiply the common factors.
4. To find LCM, multiply the factors with highest exponents.

What is the LCM of 24 and 36 by prime factorization method?

72
LCM of 24 and 36 by Prime Factorization LCM of 24 and 36 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 23 × 32 = 72. Hence, the LCM of 24 and 36 by prime factorization is 72.

## What is the LCM of 726 and 693?

What is the LCM of 2 4 and 6?

12
Answer: LCM of 2, 4, and 6 is 12.

What does LCM mean in math?

least common multiple
Definition of least common multiple 1 : the smallest common multiple of two or more numbers.

### How do you find the LCM of 12 and 16?

The LCM of 12 and 16 is 48. To find the LCM (least common multiple) of 12 and 16, we need to find the multiples of 12 and 16 (multiples of 12 = 12, 24, 36, 48; multiples of 16 = 16, 32, 48, 64) and choose the smallest multiple that is exactly divisible by 12 and 16, i.e., 48.

How to find GCF and LCM?

Prime numbers are numbers that cannot be divided by any other number in mathematics. In this method, you must divide all of the numbers by a prime number such as 2, 3, or any other number. Finally, all of those prime factors will be properly multiplied to find the GCF and LCM .

What are two ways to find prime factorization?

There are two methods of finding the prime numbers to a composite number: by factor tree, and by factoring. The two methods actually have the same concept. They just differ in the illustration for better understanding. Factor tree is used by finding any pair of number whose product is the given number.

## How to find the least common multiple (LCM)?

List the multiples of each number until at least one of the multiples appears on all lists

• Find the smallest number that is on all of the lists
• This number is the LCM
• How do you find the prime factorization using exponents?

There are certain rules to write prime factorization using exponents’ term. In prime factorization exponent form first we factor the number after that if any factor of given number is coming more than once then we count the same factors and write in exponents.
