Factors of 15 = 1, 3, 5 and 15. 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.
What is the common multiple for 10?
Multiples of 10 are 10, 20, 30, 40, 50, 60, etc.
How do you find the highest common multiple?
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.
What is the highest common multiple of 10 and 12?
2
Answer: HCF of 10 and 12 is 2.
What do 12 and 10 both go into?
The biggest common factor number is the GCF number. So the greatest common factor 12 and 10 is 2.
Is it possible to find the highest common multiple?
To find a common multiple, you have to write the factors of the given set of numbers. 10=2×5. 15=3×5. 25=5×5. 55=5×11. Here, as you can see 5 is the highest common multiple in the given set of numbers. Similarly you can do this in all type highest common multiple questions. Ask me if you have any doubts. Deb P. Choudhury, Ph.D.
Which is the highest common factor of two numbers?
Highest common factor. A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one. For example,…
Which is an example of a common multiple?
A multiple is a number that can be divided by another number without a remainder. Two numbers have a common multiple if the same number is a multiple of both those numbers. For example, the number 12 is a common multiple of the numbers 3 and 4. We know this because both 3 and 4 divide into 12 without a remainder.
When do two numbers have a common multiple?
Two numbers have a common multiple if the same number is a multiple of both those numbers. For example, the number 12 is a common multiple of the numbers 3 and 4. We know this because both 3 and 4 divide into 12 without a remainder. common multiple A common multiple is a multiple of two or more numbers. Find three common multiples of 5 and 6.
