As product of its prime factors: 3*3*5 = 45
As a product of its prime factors: 3*3*5 = 45 or as 32*5 = 45
3 x 3 x 5 = 45
As a product of its prime factors: 3*3*5 = 45 Or as: 23+19+3 = 45
3 x 3 x 5 = 45
3 x 3 x 5 = 45
Product of its prime factors are: 3*3*5 = 45
3 x 3 x 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)
It isn't. 32 and 45 have no common prime factors, so the LCM is their product, 1440
3 x 3 x 5 = 45
The Prime Factors of 45 are 3, 5
