What is the least common multiple of 7 and 24?
By doing the Prime factorization:
And since there's isn't any common factor We need all the prime factors listed
A teacher will expect the prime number method. Just for the hell of it this is a different approach!
We have two numbers ; 24 and 7
I am going to count the 24's. However lets look at this value.
24 can be 'split' into a sum of 7's with a remainder. So each 24 consists of:
If we sum columns of these we will get the 3 summing to a value into which 7 will divide exactly. When this happens we have found our least common multiple.
REMEMBER WE ARE COUNTING THE 24's
We have a count of 7 so the value is
