(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.
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.
The greatest common factor of 45 and 105 is 15.
3 is a factor and dividing by 3 gives x + 15 = 8x
17 plus 15 plus 13 equals 45.
