What are numbers that have factors of 2 and 5?
You can also think about factors in terms of division: The factors of a number include all numbers that divide evenly into that number with no remainder. Consider the number 10. Since 10 is evenly divisible by 2 and 5, you can conclude that both 2 and 5 are factors of 10.
What number is a factor of 2 and 3?
The factors of 2 and 3 are 1, 2 and 1, 3 respectively. There are 3 commonly used methods to find the HCF of 2 and 3 – prime factorization, long division, and Euclidean algorithm.
Which number has 3 as a factor?
As it turns out, the only positive integers with exactly three factors are the squares of primes. For instance, the factors of 9 are 1, 3, and 9, andand the factors of 49 are 1, 7, and 49.
What is a multiple of 3 and 5?
Step 1: List a few multiples of 3 (3, 6, 9, 12, 15, 18, 21, . . . ) and 5 (5, 10, 15, 20, 25, 30, 35, . . . . ) Step 2: The common multiples from the multiples of 3 and 5 are 15, 30, . . . Step 3: The smallest common multiple of 3 and 5 is 15.
What number has exactly 5 factors?
Explanation: The only two numbers in the range [1, 100] having exactly 5 prime factors are 16 and 81. Factors of 16 are {1, 2, 4, 8, 16}. Factors of 8 are {1, 3, 9, 27, 81}.
What are the factors of three?
Factors of 3 are 1 and 3 only. Note that -1 × -3 = 3.
What is factor tree?
Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.
What is the common factor of 2 and 3?
1
Since, 1 is the only common factor between 2 and 3. The Greatest Common Factor of 2 and 3 is 1.
What is the LCM of 3 and 5?
15
Answer: LCM of 3 and 5 is 15.
