How do I find the 2 numbers when their LCM and HCF are given?
First we need to find the highest common factor (H.C.F.) of 15 and 18 which is 3. Then we need to find the lowest common multiple (L.C.M.) of 15 and 18 which is 90. Therefore, product of H.C.F. and L.C.M. of 15 and 18 = product of 15 and 18. or, L.C.M.
What is the greatest common factor of 3 and 30?
3
The GCF of 3 and 30 is 3.
What is the LCM of 30 and 4?
60
Answer: LCM of 4 and 30 is 60.
What is the LCM for 30?
Multiples of 30: 30, 60, 90, 120, 150, 180… The lowest common multiple of 25 and 30 is 150.
What is the difference between the LCM and HCF of the numbers 20 30 and?
Now, the LCM (Least common multiple) in the above three equations are given by the common factor along with other factors. Similarly, the HCF (Highest common factor) in the above three equations is $ = 2 \times 5 = 10$. Therefore, the required answer – LCM and HCF of $20,30$ and $40$ are $120$ and $10$.
What is the GCF of 2 and 3?
1
The GCF of 2 and 3 is 1.
What is the HCF of 30?
Factors of 30 (Thirty) = 1, 2, 3, 5, 6, 10, 15 and 30. Factors of 24 (Twenty four) = 1, 2, 3, 4, 6, 8, 12 and 24. Therefore, common factor of 30 (Thirty) and 24 (Twenty four = 1, 2, 3, and 6. Highest common factor (H.C.F) of 30 (Thirty) and 24 (Twenty four = 6.
What is the LCM of 3 8 times HCF?
LCM × HCF = Product of the Numbers. Suppose A and B are two numbers, then. LCM (A & B) × HCF (A & B) = A × B. Example: If 3 and 8 are two numbers. LCM (3,8) = 24. HCF (3,8) = 1. LCM (3,8) x HCF (3,8) = 24 x 1 = 24. Also, 3 x 8 = 24. Hence, proved.
How do you find the product of HCF and LCM?
The formula which involves both HCF and LCM is: Product of Two numbers = (HCF of the two numbers) x (LCM of the two numbers) Say, A and B are the two numbers, then as per the formula; A x B = H.C.F.
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 HCF of more than 3 numbers?
The above steps can also be used to find the HCF of more than 3 numbers. Example: Find the HCF of 144 and 160 by division method. Since 160>144, so the dividend will be 160 and the divisor will be 144. Hence, we can see here 16 is the highest number which divides 160 and 144. To calculate the LCM of two numbers 60 and 45.
