BYJU’S online GCF calculator tool makes the calculation faster, and it displays the GCF in a fraction of seconds. What is GCF? GCF or Greatest Common factor of two numbers is the value that can exactly divide the two numbers.

Divide 15 by 3, to get: 15/3 = 5 and also 15/5 = 3 (So, 3 and 5 are the factors of 15) Thus, the maximum factors we can get here are four, i.e., 1, 3, 5 and 15. Therefore, the factors of 15 are 1, 3, 5 and 15. Prime Factorisation of 15. By prime factorisation of 15, we will get the prime numbers or prime factors, that evenly divides 15.

Hence, the GCF of 80 and 125 is 5. Example 4: Find the greatest common factor of 15, 50 and 75 using the prime factorization method. Solution: Write each number as a product of prime factors: \(15 = 3 \times 5\) \(45 = 3 \times 3 \times 5\) \(75 = 3 \times 5 \times 5\) The common prime factors are \( 3 \times 5 \) Hence, the GCF of 15, 45 and ...

The HCF of 15 and 20 is 5. The greatest number that divides 15 and 20 perfectly without leaving any residue is the HCF of 15 and 20. The factors of 15 and 20 are 1, 3, 5, 15 and 1, 2, 4, 5, 10, 20, respectively. The long division, listing common factors, and prime factorisation are the three most prevalent methods for calculating the HCF of 15 ...

The GCF (Greatest Common Factors) is also known as HCF. The prime factors of 15 = 3 × 5. The prime factors of 25 = 5 × 5. The common factors are = 5. ∴ HCF (15, 25) = 5. Hence, the required HCF of 15 and 25 is 5.

The HCF of 15 and 35 is the divisor after repeated division with the remainder as zero. No further division can be done. Hence, HCF (15, 35) = 5. HCF of 15 and 35 by Listing Common Factors. The HCF of 15 and 35 by listing common factors is: Factors of 15: 1, 3, 5, 15. Factors of 35: 1, 5, 7, 35. There are 2 common factors of 15 and 35, and they ...

LCM of 7 and 15 is 105. Using the multiples of 7 and 15, the value which is evenly divisible by 7 and 15 gives the LCM value. Least common multiple of 7 and 15 is the common multiple we obtain with the help of the multiplication operation. (7, 14, 21, 28, 35, ….) and (15, 30, 45, 60, 75, ….) are the multiples of 7 and 15.

We can see that G.C.F of (15 w), (65) is 5 Now we will use the GCF to factor the expression 15 w + 65 = 3 ( 3 w ) + 5 ( 13 ) { R e w r i t e t h e e x p r e s s i o n } = 5 ( 3 w + 13 ) { D i s t r i b u t i v e p r o p e r t y }

GCF and LCM In mathematics, a factor of a natural number is the number that divides a number and results in zero as a remainder. On the other hand, the multiple of a natural number is a number that is obtained by multiplying a given number with another natural number.

The HCF of 3 and 15 by using the long division method is shown below: HCF (3, 15) = 3. HCF of 3 and 15 by Listing Common Factors. We list all the factors of given numbers to determine their Highest Common Factor in this method. The following are the factors of 3 and 15: Factors of 3: 1, 3. Factors of 15: 1, 3, 5, 15. Thus, HCF (3, 15) = 3 ...
