how to slove a LCM and HCF question and please give me a eg of a question nand the steps for it.
Answers
Step-by-step explanation:
lcm is lowest common factor and hcf is highest coomon multiple
Answer:
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.
Formula for HCF and LCM:
Product of Two numbers = (HCF of the two numbers) x (LCM of the two numbers)
Step-by-step explanation:
Take an example of finding the highest common factor of 144, 104 and 160.
Now let us write the prime factors of 144, 104 and 160.
144 = 2 × 2 × 2 × 2 × 3 × 3
104 = 2 × 2 × 2 × 13
160 = 2 × 2 × 2 × 2 × 2 × 5
The common factors of 144, 104 and 160 are 2 × 2 × 2 = 8
Therefore, HCF (144, 104, 160) = 8
