The highest common factor of 15 and 45 is 15
(x+3)(x+15)
15 x 45 = (15 x 40) + (15 x 5)
(z + 15)(z + 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
x2 + 18x + 45 = (x + 15)(x + 3).
(x + 15)(x - 3)
HCF of 15 and 45 is 15
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.
45
The greatest common factor of 15, 45, and 60 is 15
15 is a factor of 45, so the LCM is 45.
45 + 15 =60
