Question

Find the common factor of the given pair number
13. 16 and 24 - 16 Fadoro+19=C
14. 20 and 30 -
15. 48 and 56 -
16. 12 and 18 -​

Answer 1

Step-by-step explanation:

16 and 24

20 and 30

48 and 56

12 and 28

Answer 2

a) The common factor of 16 and 24 is 8.

⇒ 16,24 = 2(8,12) = 2.2(4,6) = 2.2.2(2,3)

Now, no more factors are common. Thus, the common factor of 16 and 24 is  8 (2*2*2).

b) The common factor of 20 and 30 is 10.

⇒ 20,30 = 10(2,3)

c) The common factor of 48 and 56 is 8.

⇒ 48,56 = 2(24,28) = 2.2(12,14) = 2.2.2(6,7)

The common factor of 48 and 56 is 2*2*2 = 8

d) The common factor of 12 and 18 is 6.

⇒ 12,18 = 2(6,9) = 2.3(2,3)

The common factor of 12 and 18 is 2*3 = 6
