Question

Identify the twin prime numbers.

• A. 59 & 61
• B. 11 & 17
• C. 47 & 49

Answer 1

The correct option is A 59 & 61

Twin Prime: The difference between the prime numbers should be $2$.
Prime Number: A number which has only two factors, one and itself.

Given, $47\&49;11\&17;59\&17$
$47=47\times 149=7\times 7=1\times 49$
$49$ is not a prime number.

$11=11\times 117=17\times 117-11=6$
$17\&11$ are not twin prime numbers.

$59=59\times 161=61\times 161-59=2$

$59\&61$ are twin prime numbers.
