Given:
Number 2000
To find:
Find the largest cube number less than 2000
Solutions:
A perfect cube number is a number which can be written in the form of a³
Example: 8 = 2³, 27 = 3³
To find the largest cube number less than 2000
write 2000 as product of its prime factors
2000 = 2 × 2 × 2 × 2 × 5 × 5 × 5
Now group the above factors as triplets
2 × 2 × 2 × 2 × 5 × 5 × 5 = (2×2×2)× 2 × (5×5×5) = 2³ 5³ 2
Here one two is left alone
We need a number which a largest cube but less than 2000
So Remove 2
The cube number = 2³ 5³ = 1000.
The largest cube number less than 2000 is 1000

Answer:
The answer to the given question is largest cube number less than 2000 is 1000.
Step-by-step explanation:
Given :
A number is given as 2000.
To find:
we have to find the largest cube number less than 2000.
Solution :
The problem is solved by a prime factorisation method.
The cube number is obtained by multiplying the number by itself two times.
A perfect cube number is a number that can be written as x³.
we have to find the factors of 2000 by the prime factorisation method.
The prime factors of the given number are 2*2*2*2*5*5*5
joining the factors as a triplet, we get the answers as
only one 2 is left with the power 1.
on ignoring the extra number, we get the value as
The value obtained is
