If there are more than 2 numbers to find and there are 2 or more divisible numbers
Divide that number by the number that is not divisible, pull that number down until all the numbers are not divisible. Then multiply all the divisors and multiply by the result. Call this technique L-shaped multiplication.
If there are 2 find numbers and there is 1 divisible number
Divide that number by the number that is not divisible, pull that number down until all the numbers are not divisible. Then multiply all the divisors and multiply by the result.
Let’s look at another example.
Find the RN. of 24 ,56,48
Things to remember today
1. What is NRCT?
2. All 3 methods of finding NCSC
If you can remember all of this, you will find out. NRCT, yes.
Do you understand? If you understand, then let’s do exercises.
