(x+3)(x+15)
(z + 15)(z + 3)
x2 + 18x + 45 = (x + 15)(x + 3).
The GCF of 15 and 45 is 15Since 15 is a factor of 45, and 15's largest factor cannot be larger than itself, the greatest common factor of 15 and 45 is 15.Since 15 is a factor of 45, it is automatically the GCF.15
(x + 15)(x - 3)
Since 15 is a factor of 45, and 15's largest factor cannot be larger than itself, the greatest common factor of 15 and 45 is 15.
15 x 45 = (15 x 40) + (15 x 5)
The answer to the LCM of 45 and 15 is 45.
The greatest common factor of 45 and 105 is 15.
First add 15 and 45. Then find the factors. 15+45=60 The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30.
3 is a factor and dividing by 3 gives x + 15 = 8x
17 plus 15 plus 13 equals 45.
