Q) Which of the following number has a total of 24 positive factors.
a) .
b) .
c) .
d) 63 * 55.
Option(d) 63 × 55, number has total 24 positive factors.
Given,
4 numbers.
To Find,
Which number has a total of 24 positive factors?
Solution,
The first option is can be written as by applying the prime factorization theorem,
=
Then the total factors will be 6 × 6 × 4 = 144.
So, this is not equal to 24.
b) , it can be written as,
= ,
which is not equal to 24.
c) In option(c) the factors are 7 × 5,
but these factors are not equal to 24.
d) Option(d) i s 63 × 55,
× × × .
And the factors are = 3 × 2 × 2 × 2
That will be equal to 24.
Hence, the number 63 × 55, is the number that has a total of 24 positive factors.
