The GCF is the smallest shared prime factor for each term.
The LCM is the smallest whole number that both numbers share as multiples.
For example, take #16.
Factors of 25: 1 , 5, 25
Factors of 75: 1 , 3, 5, 15, 25 ,75
The GCF that is shared would then be 25.
The smallest multiple that both share as multiples:
Multiples of 25: 25, 50, 75, etc.
Multiples of 75: 75, etc.
The LCM that is shared would then be 75.

Answer:
254
Step-by-step explanation:
63.5 ÷ 0.25 =
= 63.5 ÷ 1/4
= 63.5 × 4
= 254
Answer: 254.
Answer:
-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.
Step-by-step explanation:
-7x-2y=-21
-2y=7x-21
y=-7/2x-21/2
y=-7/2x-10.5
Hope this helps!
Answer: M= slope
M= -1/5
Step-by-step explanation:
M= the change in y over the change in x so you would do 1-4 over 13-(-2) which gives you -3 over 15 which is simplified to give you the answer which is -1/5.
