3 and 5
Prime factors of 18 are 2 and 3 Prime factors of 45 are 3 and 5
The factors of 45 are 1, 3, 5, 9, 15, 45 Of those, 3 and 5 are prime numbers. The prime factors of 45 are 3 and 5.
As a product of its prime factors: 3*3*5 = 45 Or as: 23+19+3 = 45
Distinct prime factors are 3 and 5.
To figure this out you should first express the numbers as the product of their prime factors: 27 = 3x3x3 45 = 3x3x5 The next step is to identify any common prime factors. Both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus 9 is the HCF of 27 and 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)
The number with prime factors of 3, 3, and 5 is 45. This is because 3 x 3 x 5 = 45. Prime factors are the prime numbers that multiply together to make a composite number, and in this case, the prime factors of 45 are 3 and 5.
The Prime Factors of 45 are 3, 5
45 has two prime factors: 3 and 5.
The prime numbers between 45 and 60 are 47, 53, and 59. The common factors of 45 and 60 are 1, 3, 5, and 15. The greatest common factor of 45 and 60 is 15.
The factors of -45 are 1, 3, 5, 9, 15, 45 and their negatives. The prime factors are 3 and 5.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. neither 45 nor 54 are prime.
