What is the LCM and HCF of 4?
HCF of 4 and 6 by Prime Factorization Prime factorization of 4 and 6 is (2 × 2) and (2 × 3) respectively. As visible, 4 and 6 have only one common prime factor i.e. 2. Hence, the HCF of 4 and 6 is 2.
What are the LCM multiples of 4?
Example: Find the least common multiple of 4, 6, and 8 Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, Multiples of 6 are: 6, 12, 18, 24, 30, 36, Multiples of 8 are: 8, 16, 24, 32, 40.. So 24 is the least common multiple (I can’t find a smaller one!)
What is the highest common factor 4?
The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example, 8 and 12 have common factors of 1, 2 and 4. The highest common factor is 4.
How do you find the LCM of 4?
- Finding LCM by listing the multiples. Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48,… Multiples of 8 = 8, 16, 32, 40, 48, .. Multiples of 12 = 12, 24, 36, 48,..
- Finding LCM by Prime Factorisation. 4 = 2 x 2. 8 = 2 x 2 x 2. 12 = 2 x 2 x 3.
- LCM by Long Division Method. Divisor. Divisor = 2. Divisor = 2.
What is the GCF of 4 and 4?
We found the factors and prime factorization of 4 and 4. The biggest common factor number is the GCF number. So the greatest common factor 4 and 4 is 4.

What’s the LCM of 4 and 4?
4
The LCM of 4 and 4 is 4.
How many factors do 4 have?
So the factors of the number 4 are 1, 2, and 4.
What is the LCM of 4 and 4?
How many factors are there in 4?
What is the factor of 4?
1, 2 and 4
In other words, if we multiply a pair of numbers together, which results in the original number 4, the numbers are the factors of 4. As 4 is an even composite number, it has more than two factors. Thus, the factors of 4 are 1, 2 and 4.
How many multiples of 4 are there?
Answer: 60 multiples of 4 lie between 10 and 250. Let’s find the multiples of 4 that lie between 10 and 250. We need to find the number of terms (n) in the progression which ends at 248. Therefore, there are 60 terms, which means there are 60 multiples of 4 between 10 and 250.
What are common factors of 4?
The factors of 4 are 1, 2 and 4.
What is the highest common multiple of 3 and 4?
Answer: HCF of 3 and 4 is 1. Explanation: The HCF of two non-zero integers, x(3) and y(4), is the highest positive integer m(1) that divides both x(3) and y(4) without any remainder.
