Question

4) complete the missing factor tree. a) 18 B) 96 5) ​

Answer 1

Answer:

a) 18  

Basically, we branch out 18 into its prime factors. So, the prime factorization of 18 is 18= 2 × 3 × 3. A factor tree is not unique for a given number. Instead of expressing 18 as 2 × 9, we can express 18 as 3 × 6.

b) 96  

The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96 and the factors of 19 are 1, 19. 96 and 19 have only one common factor which is 1.

c)5

Since 5 is a prime number, it has only two factors. Factors of 5 are 1 and 5.

Hope it helps.
