6 and 8 are not prime numbers. Nor are they greater than 40 and less than 50.
Numbers with exactly 6 factors are perfect squares of prime numbers. The prime factorization of a number with exactly 6 factors is in the form ( p^2 ), where ( p ) is a prime number. There are 10 prime numbers less than 30: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. So, there are 10 numbers less than 30 that have exactly 6 factors.
2 5 6
51 = 3*17
No, there are four.
No.
6 and 8 are not prime numbers. Nor are they greater than 40 and less than 50.
No. There are only 4.
2 5 6
51 = 3*17
No, there are four.
It is 6 because 2*3 = 6
All prime numbers except 2, 3 and 5 are greater than 6.
23 is the answer
They are all prime numbers ============================= They're also all: -- integers -- greater than 6 -- less than 30 -- odd numbers -- less than 4 syllables
It can be 1, 2, 4, 6 or 8.
solution: we know that there are 25 prime numbers are between 1-100 and 168 prime numbers less than 1000. 100 x 100=10000(5 digits) 999 x 999=998001(6 digits) 1000 x 1000=1000000(7 digits) so our answer should be same as the number of prime numbers between 100 to 999. hence, 168-25=143. 143 prime numbers will be there less than 1000 whose square has 5 or 6 digits.
