Answer:
1. Factors of 18: 1,2,3,6,9,18
2. Common factor: 1,2,4
3. Common factor: 6,12,18,24,30,36,42,48,54,60,66,72,78,84,180....
4. co-prime numbers
5. a. last digit
6. b. even numbers
7. 5 and 9 and 2 and 13
8. c. 5
9. c. 6
10. b. 27
Step-by-step explanation:
1. Factors mean that the number 18 comes in which numbers's table.
2. First write the factors of 16 and 20.
Then circle the common or same numbers in both the lists of factors.
Then the circled nos. will be the common factors.
3. First write the table of 3 and 6.
Then circle the common or same numbers in both the tables.
Then the circled nos. will be the common multiples.
4. co-prime no.
5. last digit because to check the divisibility of
- 2= last digit should be the multiple of 2.
- 5= last digit should be 5,0
- 10= last digit should be 0.
6. All the multiples of 2 are even.
7. They have common factor as 1.
8. First write the factors of 15 and 25.
Then circle the common or same numbers in both the lists of factors.
Then the circled nos. will be the common factors.
9. 6
10. 27
