Which pair of numbers has the LCM of 150?
Answer: d)15,50 is the right answer.
What numbers have a HCF of 15?
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 150?
150 = 1 × 2 × 3 × 5 × 5. 350 = 1 × 2 × 5 × 5 × 7. Common factor of 150 and 350 = 1, 2, 5, 5. Highest common factor of 150 and 350 = 2 × 5 × 5 = 50.
Is the product of two Coprime numbers is 2021 then find the LCM of these numbers?
R D Sharma – Mathematics 9 The LCM of the two numbers is equal to 2021. Solution: Co-prime numbers are the numbers whose highest common factor ( HCF) is 1.
What is the HCF of 15 and 45?
Therefore, the greatest common factor of 15 and 45 is 15.
What is the LCM of 2 numbers if HCF is 15?
It has many answers actually cause u can’t say the LCM of 2 numbers just by their hcf. Example hcf of 45 and 30 is 15… 75 and 60 is 15 but their LCMS are different. Hope u understand. If the HCF is 15, the LCM would be any multiple of 15 that is either equal to or more than highest of the two given numbers.
What is the LCM of 15 and 30?
If the HCF of the two numbers is 15 then the two numbers are 15*a and 15*b where ‘a’ and ‘b’ are integers. LCM is a least value of the number divisible by both 15*a and 15*b. So if you are expecting to know the smallest value for the LCM then a=1 and b= 2 could be a possible solution.This gives the LCM of 15 and 30 as 30.
What is the HCF and lcm of 25 35 and 45?
From the above expression, we can say 5 is the only common factor for all the three numbers. Therefore, 5 is the HCF of 25, 35 and 45. Example: Find the Least Common Multiple of 36 and 44. Solution: Given, two numbers 36 and 44. Let us find out the LCM, by division method.
How to find the least common factor (LCM) of two numbers?
Out of other ways, one way to find the LCM of given numbers is as below: List the prime factors of each number first. Then multiply each factor the most number of times it occurs in any number. If the same multiple occurs more than once in both the given numbers, then multiply the factor the most number of times it occurs.
