or Lowest Common Multiple is the smallest Integer that is as well as a multiple of the given Numbers.
Example: What is the LCM of 2 and 3?
It is 6 because
It is used not very commonly.Word Problem:
Sammy is playing on a Merry-Go-Round.
the people behind him plus
the people in front of him plus 1 equals the number of total people on the merry-go-round . How many people are there in the Merry-Go-Round?Answer:
There are 13 people on the Merry-Go-Round.
of the people behind him plus
in front of him plus one is the total amount.
You cannot make a portion of a person! So we know that the number of people ahead of him is a multiple of 4 and the number of people behind him is a multiple of 3.
Find the LCM of 3 and 4.
LCM of 3 and 4 is 12.
So the total number of people on the merry go round
or Highest Common Factor is the greatest integer which is also a factor of the given numbers.
For Example, find the HCF of 4 and 6.
Factors of 4:
Factors of 6:
Find the common Factors.
They are 1 and 2. 2 is bigger than 1, so the HCF of 4 and 6 is 2.Word Problem:
Simplify the fraction Answer:
We know that the HCF of 12 and 30 is 6.
Now divide 12 and 30 by 6.
We will get 2 and 6.
Hope it helps.
