They have several applications.
To add, subtract, or just compare two fractions, you need to convert both fractions to a common denominator. The least common multiple is usually used, although any common multiple would work in this particular case (e.g., just multiplying the two denominators).
To simplify a fraction, you divide the numerator and the denominator by the same number. If you divide them by the greatest common factor, no further simplifications are possible.

What is the HCF and LCM of the numbers 526 and 213?
hcf: 1 lcm: 112,038
Can HCF and LCM of two numbers be 27 and 288?
No. The LCM MUST be a multiple of the HCF.
What are the four methods to find LCM and HCF?
hcf or gcf. first write the numbers the number can be multiplied to get it,you will have more than one or two numbers and when you see you have the number in a row then look for the highest number in all row .LCM do same as hcf but the numbers you got just multiply.try 2,4,16,24,48 you must get for LCM get 144 and for hcf or gcf you must get 24.
Can two numbers have 16 as their HCF and 380 as their LCM?
LCM = product/HCF so product = LCM/HCF in this case 380/16 which is 23.75, so the answer to your question is no.
How do you find two numbers if HCF and LCM are known?
The product of the GCF and the LCM of two numbers is equal to the product of the original two numbers. Multiply the GCF and the LCM. The original two numbers will be another factor pair of that total. Find the factor pair that has that GCF and LCM.
