2 x 2 x 2 x 3 = 24
2 x 3 = 6, the GCF
18/6 = 3
24/6 = 4
18/24 = 3/4

What is the least common multiple of 36 and 45 and 54?
It is 9 derived as: Prime Factors of 36: 2x2x3x3 Prime Factors of 45: 5x3x3 Prime Factors of 54: 2x3x3x3 The common prime factors of all the three numbers are 3x3 = 9 To check you answer: 1. Divide all the three numbers by 9 and they shall be perfectly divisible 2. Try and divide non common factors of each number by other two, it would not be perfectly divisible (i.e. Try and divide 54 by 5)
What does common prime factors mean?
When two or more numbers have one or more of the same primes as factors, those prime factors are called common prime factors. For example, the prime factors of 6 are 2 and 3, and the prime factors of 21 are 3 and 7, so 3 is a common prime factor of 6 and 21.
How can you use prime factorization to write a fraction in simplest form?
The idea is to divide numerator and denominator of a fraction by any common factors. Prime factorization is simply used to find all possible factors.
How do you do the prime factorization of number?
Divide a number and its factors by prime numbers until all the factors are prime. 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. 2 x 3 x 5 x 7 = 210

What are the common factors of 17 and 62?
17 is a prime number so no other number will divide into it
What is the LCM of 28 and 21?
To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 21 are 3 and 7. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 7. Therefore, the lowest common multiple is 21 x 28 ÷ 7 = 84
How do you divide prime factors?
Prime factors can be divided only by 1 and by themselves.
How do you simplify fractions using prime numbers?
To simplify a fraction using prime numbers, find the prime factors of both the numerator and denominator. Then, divide the numerator and denominator by their common prime factors. Repeat this process until there are no common prime factors left. The resulting fraction will be simplified to its simplest form.
