HERE IS YOUR ANSWER ROSHNI

4(3×3×101+1)
4(9×101+1)
4(909+1)
4(910)

4(909) IS NOT A PRIME NUMBER BECAUSE IT HAS A FACTOR 4

THEREFORE, 3×12×101+4 IS A COMPOSITE NUMBER

Hii Roshni, here is your answer

=> 3 x 12 x 101 +4. ( Take 4 as common)
=> 4(3 x 3 x 101 + 1 )
=> 4( 9 x 101 + 1 )
=> 4 ( 909 + 1 )
=> 4 ( 910 ) = ( 3640)

4 (910) this is not a prime number
because it have a factor 4
So, this is composite number.

^_^ HOPE IT HELP YOU. ^_^
