Quick Answer: What Is The LCM Of 9 12 And 18?

What is the HCF of 9 12 and 18?

Find the highest common factor (H.C.F) of 12 and 18.

Factors of 12 = 1, 2, 3, 4, 6 and 12.

Factors of 18 = 1, 2, 3, 6, 9 and 18.

Therefore, common factor of 12 and 18 = 1, 2, 3 and 6.

Highest common factor (H.C.F) of 12 and 18 = 6 [since 6 is the highest common factor]..

What is the LCM and GCF of 9 and 12?

93=3 and 123=4 . By making factor trees you can identify the largest common factors of two numbers. 9=3⋅3 and 12=2⋅2⋅3 , in this case the only common factor is 3 and therefore the greatest.

What is the HCF of 18 and 24?

We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number. So the greatest common factor 18 and 24 is 6.

What is the HCF of 100?

Factors of 100 = 1, 2, 5, 10, 20, 50 and 100. Factors of 150 (one hundred fifty) =1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150. Therefore, common factor of 100 and 150 = 1, 2, 3, 5, 10 and 50. Highest common factor (H.C.F) of 900 and 270 = 50.

What is the least common multiple of 9 15 and 18?

The LCM of 9,15,18 9 , 15 , 18 is 2⋅3⋅3⋅5=90 2 ⋅ 3 ⋅ 3 ⋅ 5 = 90 .

What is the GCF of 5 and 7?

The factors of 7 are 7, 1. The common factors of 5 and 7 are 1, intersecting the two sets above. In the intersection factors of 5 ∩ factors of 7 the greatest element is 1. Therefore, the greatest common factor of 5 and 7 is 1.

What is the LCM of 3 and 9?

Least common multiple (LCM) of 3 and 9 is 9.

What is the LCM of 3 and 4?

The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of. Like the LCM of 3 and 4 is 12, because 12 is the smallest number that 3 and 4 are both factors for.

What is the HCF of 15 and 18?

The factors of 18 are 18, 9, 6, 3, 2, 1. The common factors of 15 and 18 are 3, 1, intersecting the two sets above. In the intersection factors of 15 ∩ factors of 18 the greatest element is 3. Therefore, the greatest common factor of 15 and 18 is 3.

What is the HCF of 9 and 11?

The factors of 9 are 9, 3, 1. The common factors of 11 and 9 are 1, intersecting the two sets above. In the intersection factors of 11 ∩ factors of 9 the greatest element is 1. Therefore, the greatest common factor of 11 and 9 is 1.

What is the HCF of 15 and 30?

The common factors of 15 and 30 are 1, 3, 5, and 15. The greatest common factor is 15.

What is the HCF of 15 and 20?

5Greatest common factor (GCF) of 15 and 20 is 5. We will now calculate the prime factors of 15 and 20, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 20.

What is the common factor of 9 and 12?
