What is the H.C.F of 15?
Factors of 15 (Fifteen) = 1, 3, 5 and 15. Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of 15 (Fifteen) and 35 (Thirty five) = 1 and 5. Highest common factor (H.C.F) of 15 (Fifteen) and 35 (Thirty five) = 5.
What is the HCF of 10 and 15?
5
Answer: HCF of 10 and 15 is 5. Explanation: The HCF of two non-zero integers, x(10) and y(15), is the highest positive integer m(5) that divides both x(10) and y(15) without any remainder.
What is the LCD for 10 and 15?
What is the Least Common Multiple of 10 and 15? Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least common multiple (LCM) of 10 and 15 is 30.
What is the LCM of 15?
The LCM of 15 and 20 is 60. To find the LCM (least common multiple) of 15 and 20, we need to find the multiples of 15 and 20 (multiples of 15 = 15, 30, 45, 60; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 15 and 20, i.e., 60.
What is the LCM of 10?
The LCM of 10 and 12 is 60. To find the least common multiple (LCM) of 10 and 12, we need to find the multiples of 10 and 12 (multiples of 10 = 10, 20, 30, 40 . . . . 60; multiples of 12 = 12, 24, 36, 48 . . . . 60) and choose the smallest multiple that is exactly divisible by 10 and 12, i.e., 60.

What is the HCF and LCM of 15 and 20?
Example 1: Find the HCF of 15 and 20, if their LCM is 60. Therefore, the highest common factor of 15 and 20 is 5. Example 2: For two numbers, HCF = 5 and LCM = 60.
What is the HCF of 10?
Factors of 10 = 1, 2, 5 and 10. Therefore, common factor of 15 and 10 = 1 and 5. Highest common factor (H.C.F) of 15 and 10 = 5. 5.
What is the GCF of 10 and 15?
GCF of 10 and 15 by Listing Common Factors There are 2 common factors of 10 and 15, that are 1 and 5. Therefore, the greatest common factor of 10 and 15 is 5.
Whats the LCM of 15?
What is the HCF 10 and 15?
How do you find the HCF?
How to Find HCF?
- Step 1: Write each number as a product of its prime factors. This method is called here prime factorization.
- Step 2: Now list the common factors of both the numbers.
- Step 3: The product of all common prime factors is the HCF ( use the lower power of each common factor)
How do you find HCF and LCM?
The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.
How do you find LCM?
Multiply the list of prime factors together to find the LCM….For example, for LCM (12,30) we find:
- Prime factorization of 12 = 2 × 2 × 3.
- Prime factorization of 30 = 2 × 3 × 5.
- Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.
- Therefore LCM (12,30) = 60.
What is the HCF of 15 and 12?
3
HCF Example The factors of 15 are : 1, 3, 5, 15. 1 and 3 are the only common factors (numbers which are factors of both 12 and 15). Therefore, the highest common factor of 12 and 15 is 3.
