Answer Expert Verified Co-primes are the pair of those numbers whose common factor just includes 1 and they don’t have more than two factors i.e 1 and number itself. Therefore, LCM of two co-primes is product of them. Answer→ The LCM of a and b where a and b are Co-primes is ab.
What is the LCM of two co prime numbers * 1 point their sum their difference their product their quotient?
As they do not have any common factors. So, a number which is divisible by both must at least contain them both. LCM (co – primes) = product of those co – primes. Hence option C is the correct answer.
What is the HCF of 2 Coprime numbers?
1
The HCF of two coprime numbers is always 1. For example, 5 and 9 are coprime numbers, and hence, HCF (5, 9) = 1. The LCM of two coprime numbers is always their product.
How to find the least common multiple of 6?
Example: Find the least common multiple (LCM) of 6 and 15 using the common division method. Step 1 – 2 is the smallest prime number and it is a factor of 6. Write this prime number on the left of the two numbers. For each number in the right column, continue finding out prime numbers which are their factors.
Is the least common multiple to two prime numbers always?
To check, 1260/84 = 15 and 1280/315 = 4. A similar thing happens when one of the numbers is prime and the other is composite. You can test this out for yourself with 11 and 55. The product is 605, but the LCM is less than this. What is it? Hope this helps, Stephen La Rocque>
Which is the LCM of two coprime numbers?
The LCM of two coprime numbers is always their product. 5 5 and 9 9 are coprime numbers. The sum of two coprime numbers is always coprime with their product. 5 5 and 9 9 are coprime numbers. 2 Prime numbers have only 1 as their common factor.
Which is the most common multiple of two numbers?
The multiples of a number are found by multiplying it with 1, 2, 3, 4….and so on. For example, the multiples of 4 are 4 × 1, 4 × 2, 4 × 3, 4 × 4,…or 4, 8, 12, 16 …and so on. The multiples of two numbers that are common to both the numbers are known as common multiples of those numbers.
