Quick Answer: What Is The HCF Of 5 And 7?

Whats the LCM of 5 7 and 10?

In this case, using 5 , 7 , and 10 .

The smallest common multiple of each would be 70 .

If we find the multiples of each of the numbers, we can see that no other number before 70 is common to all of them..

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 HCF of 5 and 6?

The prime factorization of 6 is: 2 x 3. The prime factors and multiplicities 5 and 6 have in common are: 1. 1 is the gcf of 5 and 6. gcf(5,6) = 1.

What is the HCF of 12?

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 HCF of 16 and 24?

8Consider the highest common factor of 16 and 24 again. The common factors are 1, 2, 4 and 8. So, the highest common factor is 8.

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 HCF of 5 and 3?

Greatest common factor (GCF) of 3 and 5 is 1. We will now calculate the prime factors of 3 and 5, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 3 and 5.

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 3/4 and 5?

The numbers are (3 x 40), (4 x 40) and (5 x 40). Hence, required H.C.F. = 40.

What is the HCF of 5 and 25?

The hcf(25,35) is 5 .

What is the least common factor of 5 and 7?

LCM(5, 7) = 5×7 = 355 = 5.7 = 7.

What is the LCM of 5/6 and 7?

2 Answers By Expert Tutors. since the three numbers in question have no factors in common, the LCM is the product of all three, namely 210.

What are the first 5 multiples of 7?

Write down the number 5 and keep adding 5 to it until you’ve written six numbers. The first six multiples of 7 are 7, 14, 21, 28, 35, and 42.

What is the HCF of 12 and 15?

The factors of 12 are : 1, 2, 3, 4, 6, 12. 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.

What is the HCF of 6 and 12?

We found the factors and prime factorization of 6 and 12. The biggest common factor number is the GCF number. So the greatest common factor 6 and 12 is 6.
