is greater
is greater
and
are equal.
A prime number is a natural number greater than that can be divided only by
and itself.
The prime numbers between and
are:
The prime numbers between and
are:
So and
are equal.
Example Question #17 : Prime Numbers

and
are equal
is greater
is greater
and
are equal
A prime number is a natural number greater than that can be divided only by
and itself.
The prime numbers between and
are:
The prime numbers between and
are:
So there are five prime numbers between and
and there are five prime numbers between
and
too. Therefore
and
are equal.
Example Question #425 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
Which of the following numbers is not a prime number between and
?
A prime number is a natural number greater than that can be divided only by
and itself. In this problem
is the only number which is not prime.
Example Question #425 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
Which one is greater?
The smallest prime number greater than
multiplied by the smallest prime number greater than
.

and
are equal
is greater
is greater
is greater
A prime number is a natural number greater than that can be divided only by
and itself. The smallest prime number greater than
is
and the smallest prime number greater than
is
. So we can write:
So is greater than
.
Example Question #13 : Prime Numbers

it is not possible to tell based on the information given.
is greater
and
are equal.
A prime number is a natural number greater than that can be divided only by
and itself.The prime numbers between
and
are:
That means there are four prime numbers between and
. So
and
are equal.
Example Question #421 : Isee Upper Level (Grades 9 12) Quantitative Reasoning
Which one is greater?
The product of the first four prime numbers
is greater
and
are equal
it is not possible to tell based on the information given.
is greater
is greater
A prime number is a natural number greater than that can be divided only by
and itself. The first four prime numbers are:
.
So their product is:
, which is greater than
.
