As a product of its prime factors: 3*3*5 = 45 or as 32*5 = 45
3 x 3 x 5 = 45
73 is a prime number, but 45 is not a prime number.
45 is NOT a prime number.
15 is a factor of 45, but it is not a prime number.
As a product of its prime factors: 3*3*5 = 45 or as 32*5 = 45
The product of two prime numbers can never be another prime number, the numbers that you multiplied are factors of the product. (example, 9 times 5 is 45, 9 and 5 go into 45)
3 x 3 x 5 = 45
The prime number after 45 is 47.
73 is a prime number, but 45 is not a prime number.
the prime number after 45 is 47
45 is NOT a prime number.
45 = 32*5
15 is a factor of 45, but it is not a prime number.
As product of its prime factors: 3*3*5 = 45
Students learn that the prime factorization of a number is the given number written as the product of its prime factors. For example, to find the prime factorization of 45, use a factor tree to find that 45 is 5 x 9, and 9 is 3 x 3. So the prime factorization of 45 is 5 x 3 x 3, or 5 x 3^2.
No, 45 is not a prime number. It is a composite number. A prime number can only be divided by 1 and itself. 45 can also be divided by 3, 5, 9, and 15.
