Answer :-
- 12 and 15 ➞ 3.
- 21 and 24 ➞ 3.
Explanation :-
Given Numbers :
- 12 and 15.
- 21 and 24.
To Find :
We have to find the common factors of these numbers.
Solution :
(A) 12 and 15.
12 = 2 × 3 × 2.
15 = 3 × 5.
Here, we can see that,
3 is common in both of the numbers.
So, Common Factor = 3.
(B) 21 and 24.
21 = 3 × 7.
24 = 3 × 2 × 2 × 2.
Here, we can see that,
3 is again common in both of them.
So, Common Factor = 3.
Therefore,
● Common Factor in 12 and 15 = 3.
● Common Factor in 21 and 24 = 3.
