Because they have only two factors whereas composite numbers have more than two factors
The first four Mersenne prime numbers are 2, 3, 5, and 7.
Those are the first four prime numbers.
2 x 3 x 5 x 7 = 210
2 is the smallest prime number.
By four prime numbers which are: 2 3 5 and 7
The first four Mersenne prime numbers are 2, 3, 5, and 7.
The first four PRIME numbers are 2,3,5,7. If you square these you get 4,9,25,49. The first four squared numbers could be 1,4,9,16
2 4 6 8
The first four prime numbers are 2, 3, 5, 7. The product of these numbers is 2 x 3 x 5 x 7 = 210
Those are the first four prime numbers.
It is: 2*3*5*7 = 210
2+3+5+7 = 17 2*17 = 34
Sure thing, honey. The first four prime numbers are 2, 3, 5, and 7. Multiply those bad boys together and you get 210. And wouldn't you know it, 210 is a composite number because it can be divided by numbers other than 1 and itself. Math can be a real hoot sometimes, can't it?
2 x 3 x 5 x 7 = 210
2 is the smallest prime number.
17 is the only prime number that is the sum of four consecutive prime numbers. 2 + 3 + 5 + 7 = 17
Okay I think it is 2520. First 4 prime numbers are; 2 3 5 7 First 4 composites are; 4 6 8 9 I put the composites into there prime factor form. 4=2*2 6=2*3 8=2*2*2 9=3*3 Therefore the prime factor of this number had to have three twos, two threes. It also had to have a 5 and a 7 because of the prime numbers. So the index form was; ?=2*2*2*3*3*5*7 ?=2520
