What is the GCF of 24 30 and 42

1 answer:

4 0

To find the Greatest Common Factor of these numbers, write down their factors
24=2 times 2 times 2 times 3
30=2 times 3 times 5
42=2 times 3 times 7
 find the numbers common to all of them and group likewise
24=(2 times 3) times 2 times 2
30=(2 times 3) times 5
42=(2 times 3) times 7
the common one among all of them is 2 times 3=6 
 the GCF=6

In circle M, diameters JL and HK each measure 16

creativ13 [48]

Answer:

3.5 cm

Step-by-step explanation:

In the picture attached, circle M is shown.

From the picture, minor arc JH measures 25°.

The length of the circle is π*Diameter = π*16 = 50.26 cm. This length is proportional to 360°. To find the length of minor arc JH, we have to use the next proportion:

50.26 cm / x cm = 360° / 25°

x = 50.26*25/360

x = 3.5 cm
