1 x 45, 3 x 15, 5 x 9
9 and 36
1 x 405, 3 x 135, 5 x 81, 9 x 45, 15 x 27
The factor pairs of 765 are: 1 × 765 3 × 255 5 × 153 9 × 85 15 × 51 17 × 45
24 + 21 = 45 24 - 21 = 3 Therefore, the two numbers are 21 and 24.
None. The ratio of two square numbers is itself a square number. 45 is not.
5 and 9
1*45=45 3*15=45 5*9=45
2*45 = 90
-45
45 & 50
They don't exist. 45 = 3*3*5 = 32*5.
3, -15
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)

What 2 numbers when multiplied will give me 14 and two thirds
