In addition to it, what is the LCM of 5'9 and 12?

**36** is the first number that occurs in both lists. So 36 is the LCM. The listing method is impractical for large numbers. Another way to find the LCM of two numbers is to divide their product by their greatest common factor ( GCF ).

However, what is the GCF of 5? รขโกโ Since 5 is the only common prime factor of 5 and 10. Hence, **GCF (5, 10) = 5**.

Be that as it may, what is the GCF of 5 and 30?

GCF of 5 and 30 by Listing Common Factors There are 2 common factors of 5 and 30, that are 1 and 5. Therefore, the greatest common factor of 5 and 30 is **5**.

What is the LCM of 9 3 and 7?

Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 9, 3, 7 i.e. **63** smallest integer divisible by all numbers. Least common multiple (LCM) of 9, 3, 7 is 63.

Answer: LCM of **7 and 7 is 7**.

Answer: LCM of 3 and 9 is **9**.

What is the LCM of 15 and 15? The LCM of 15 and 15 **is 15**.

The smallest number to appear on both lists is **60**, so 60 is the least common multiple of 15 and 20.

What is the LCM of 3, 4, and 7? Answer: LCM of 3, 4, and 7 is **84**.

Prime factorization of 5 and 10 is (5) and (2 รโ 5) respectively. As visible, 5 and 10 have only one common prime factor i.e. 5. Hence, the HCF of 5 and 10 is **5**.

FAQs on HCF of 20 and 30 The HCF of 20 and 30 is **10**. To calculate the Highest common factor (HCF) of 20 and 30, we need to factor each number (factors of 20 = 1, 2, 4, 5, 10, 20; factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30) and choose the highest factor that exactly divides both 20 and 30, i.e., 10.

There are 4 common factors of 15 and 30, that are 1, 3, 5, and 15. Therefore, the greatest common factor of 15 and 30 is **15**.

Correct answer: 18 and 24 share one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = **6** is the GCF of 18 and 24.

Answer: GCF of 4 and 5 is **1**.

Factors of 35 (Thirty five) = 1, 5, 7 and 35. Therefore, common factor of **21** (Twenty one) and 35 (Thirty five) = 1 and 7. Highest common factor (H.C.F) of 21 (Twenty one) and 35 (Thirty five) = 7.

The GCF of 4 and 30 is **2**.

Therefore, the LCM of 3, 7, and 10 is **210**.
