2 and 5 are, but 9 isnt because its factors are 1,3,and 9
The prime factors of 144 are 2, 2, 2, 2, 3 and 3 The prime factors of 225 are 3, 3, 5 and 5 The only prime numbers which are common to both are 3 and 3 ... 9
The prime factors of 200 are 2 and 5 or as a product of its prime factors 2*2*2*5*5 = 200
The following numbers less than 50 have 2 prime factors. Some are squares, having two of the same prime factor. Some have two different prime factors. The prime factors of 4 are 2 and 2. The prime factors of 6 are 2 and 3. The prime factors of 9 are 3 and 3. The prime factors of 10 are 2 and 5. The prime factors of 14 are 2 and 7. The prime factors of 15 are 3 and 5. The prime factors of 21 are 3 and 7. The prime factors of 22 are 2 and 11. The prime factors of 25 are 5 and 5. The prime factors of 26 are 2 and 13. The prime factors of 33 are 3 and 11. The prime factors of 34 are 2 and 17. The prime factors of 35 are 5 and 7. The prime factors of 38 are 2 and 19. The prime factors of 39 are 3 and 13. The prime factors of 46 are 2 and 23. The prime factors of 49 are 7 and 7.
467 is not divisible by any of those.
3 and 5 are prime numbers. This means they can't be separated into smaller factors. For comparison, 9 is not a prime number, since it CAN be separated into smaller factors (9 = 3 x 3).
2, 3, 5 are prime numbers but 9 is not a prime number
2, 3, 5, 7, 9 * * * * * 9 is not a prime. The fifth prime is 11.
2, 5 and 7
2, 3, and 5 are. 9 isn't.
2, 3, 5, yes. 9, no.
Reason 2 X 5 X 9 is Not Prime Factorization of 90The reason 2 X 5 X 9 is not the prime factorization of 90 is that 9 is not a prime number. 3 X 3 is 9, so the prime factorization of 90 is 2 X 3 X 3 X 5.
Prime numbers from 1 to 9 are: 2 3 5 and 7
10^9= (5*2)^9 = 2^9 * 5^9 pretty straightforward actually
The prime numbers from 1 to 9 are 2, 3, 5 and 7.
Prime Factorization of 90The prime factorization of 90 is not 2 X 5 X 9 because 9 is not a prime number. It can be factored into 3 X 3, which are prime numbers, so the prime factorization of 90 is2 X 3 X 3 X 5.
360/2=180, 180/2=90. 90/5=18, 18/2=9, 9/3=3; 2, 3, and 5 are all prime numbers
5 and 7
