We can calculate the sum of the terms in a geometric progression using the formula S = (a〖〖(1-r〗^n〗_ ))/((1-r)) when r < 1 and S = (a〖〖(r〗^n-1〗_ ))/((r-1))when r>1

We can calculate the sum of the terms in a geometric progression using the formula  S =  when r < 1 and  S = when r>1

One million is a natural number, in mathematics. It is a product of 1000 thousand. You might be familiar with the term million, and often, you’ve read it without understanding it. One million has six zeros (1000 x 1000). Furthermore, we can also write 1 Million as 1M.

Now, let us look at some more terms and how many zeros they have 

Did you know?

A number with 100 zeros is called googol and it looks like 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000

1 million in international numbering system

When it comes to numbers, it gets confusing, but with the help of periods, we can read and understand the value of numbers more easily. Different periods are used in the international number system, such as thousands, ten thousand, hundred thousand, millions, etc. These periods are a representation of the grouping of zeros together.

The chart below will explain to you what each period looks like in an international number system.

The international number system is bound within some rules, such as:

• Plurals must not be written in plural form. For instance, 319,322 is three hundred nineteen thousand three hundred twenty-two and not three hundred nineteen thousand three hundreds twenty-two.
• The ones and tens period must not be separated with ‘and.’ 3846 is three thousand eight hundred forty-six and not three thousand eight hundred and forty-six.
• No comma must separate the numerals in writing.

1 million in Indian number system

When we look at the Indian numbering system, we notice that the number of digits within a period varies compared to the international number system. Both the numbering systems represent the same name for  s, hundreds, thousand and ten thousand, but beyond that, the naming and the grouping of zeros within the period changes. Look at this table below to understand it more clearly:

Hence, 1 million in numbers in India refers to 10 lakhs

Value of 1 million in rupees

We are aware that the Indian system looks at money in terms of hundreds, thousands, lakhs, crores, etc. So, one million in Indian rupees can either be called 10 lakhs or 0.1 crores.

1 million = 1000000

1 million = 10 lakhs

1 million = 0.1 crore

As the place value of digits keeps varying from the international number system to the Indian number system, we can also say that one million = 1/10^th of a crore.

Other representations of one million

• 1M = 1,000,000
• 1,000,000 = 10 lakhs
• 999999 + 1 = 1000000
• 1000001 -1 = 1000000
• 1,000,000 = 1 x 10⁶
