FORMING
GREATEST AND SMALLEST NUMBER WITH THE GIVEN DIGITS:
In some cases,the given digits from
which the number to be formed are lesser than the digits in the number
formed.In such case, we need to use
Repetition of digits in formation of greatest and smallest number.
Form
Greatest and Smallest 6th
digit number.
1)
Digits: 3,7,8,4,9
Answer:
a)
Greatest Number:
Here, the number of digits given
are lesser than the digit to be formed.
So, to form greatest number with the
given digits ,the greater digit is repeated.
In the given digits, the greater
number is ‘9’, which is to be
repeated.
Step-1:
The number of digits given = 5.
The number to be formed is 6th
digit number, which need one more digit.
Step – 3: The digit 9, which is greater need to put in two
place values. i.e; Lakhs(L) ,
TenThousands(TTh) , the next greater
numbers are placed in next place values.
Lakhs (L) |
TenThousands (TTh) |
Thousands (Th) |
Hundreds (H) |
Tens (T) |
Ones (O) |
9 |
9 |
8 |
7 |
4 |
3 |
Thus the greatest
number formed is : 9,98,743.
b)
Smallest number:
The given digits are: 3,7,8,4,9
To form smallest number with the
given digits ,the smaller digit is repeated.
In the given digits, the smaller
number is ‘3’, which is to be
repeated.
Step-1:
The number of digits given = 5.
The number to be formed is 6th
digit number, which need one more digit.
Step-2
: The Ascending order of the given digits : 3
< 4 < 7 < 8 < 9 .
Step
– 3: The digit 3,
which is smaller need to put in two place values. i.e; Lakhs(L) , TenThousands(TTh) , the next smaller numbers are placed in next place values.
Lakhs (L) |
TenThousands (TTh) |
Thousands (Th) |
Hundreds (H) |
Tens (T) |
Ones (O) |

2)
Digits : 3 , 1 , 8 , 0
a)
Greatest Number:
Here, the number of digits given
are lesser than the digit to be formed.
So, to form greatest number with the
given digits ,the greater digit is repeated.
In the given digits, the greater
number is ‘ 8’, which is to be
repeated.
Step-1:
The number of digits given = 4.
The number to be formed is 6th
digit number, which need two more digits.
Step-2: Descending Order of the given digits: 8 > 3 > 1 >0 .
Step
– 3: The digit 8,
which is greater need to put in two place values. i.e; Lakhs(L) , TenThousands(TTh) , the next greater numbers are placed in next place values.
Lakhs (L) |
TenThousands (TTh) |
Thousands (Th) |
Hundreds (H) |
Tens (T) |
Ones (O) |
8 |

Thus the greatest
number formed is : 8,88,310 .
b)
Smallest number:
The given digits are: 3 , 1 , 8 , 0 .
To form smallest number with the
given digits ,the smaller digit is repeated. Here, digit ‘ 0 ‘ is in the given
digits. So, we need to check the next smaller number which is smaller in the
given digits i.e; ‘1’.
First, digit ‘1’ has to put in greatest place value,then the
digit ‘0’ is repeated three times in the next corresponding place values followed
by next three digits in the next place values to form smallest 6th digit number.
In the given digits, the smaller
number is ‘0’, which is to be
repeated.
Step-1:
The number of digits given = 4.
The number to be formed is 6th
digit number, which need two more digits.
Step-2
: The Ascending order of the given digits : 0
< 1 < 3 < 8 .
Step
– 3: The digit ‘1’, which is smaller need to put greatest
place value . i.e; Lakhs(L) , digit ‘0’
is placed in TenThousands(TTh) ,Thousands(Th) ,Hundreds(H) , the next smaller
numbers are placed in next place values.
Lakhs (L) |
TenThousands (TTh) |
Thousands (Th) |
Hundreds (H) |
Tens (T) |
Ones (O) |
1 |
0 |
0 |
0 |

8 |
Thus, the smallest number formed is
: 1,00,038.
The

the given digits:
