How to Read a Large Number?
To read a
large number easily, we split the number into groups. We separate the groups by
using comma or a space between them. The grouping of places is done from the
right. The first group is ones group it has 3 places from the right. The second
and the third group is grouped under thousands. The second and third groups
have the next two places each.
The sixth place from the right is called lakhs place.
Now, let us
read the number 145124. We place comma after 3digit from the right and then
after 2 digits. The number is written as 1,45,124. In the place value chart it
is written as shown below.
1. Read the numbers written in the placevalue chart below. Write them in words:
(i) Sixtyseven thousand fortysix
(ii) Four lakh eighty thousand seven
(iii) Three lakh forty five thousand eighty
(iv) Three lakh ninetythree thousand two hundred four
(v) Seven lakh one thousand eight hundred ninety four
(vi) Two lakh thirteen thousand six hundred twentyeight

The properties of factors are discussed step by step according to its property. Property (1): Every whole number is the product of 1 and itself Every whole number is the product of 1 and itself so Each number is a factor of itself.
What are multiples? ‘The product obtained on multiplying two or more whole numbers is called a multiple of that number or the numbers being multiplied.’ We know that when two numbers are multiplied the result is called the product or the multiple of given numbers.
The properties of multiples are discussed step by step according to its property. Every number is a multiple of 1. Every number is the multiple of itself. Zero (0) is a multiple of every number. Every multiple except zero is either equal to or greater than any of its factors
