Question

write prime factorisations of 16,28,38.​

Answer 1

Answer:

Step-by-step explanation:

38 is a composite number. 38 = 1 x 38 or 2 x 19. Factors of 38: 1, 2, 19, 38. Prime factorization: 38 = 2 x 19.Jan

16 is a composite number, and it is 4 squared. 16 = 1 x 16, 2 x 8, or 4 x 4. Factors of 16: 1, 2, 4, 8, 16. Prime factorization: 16 = 2 x 2 x 2 x 2, which can also be written 16 = 2⁴.

28 is a composite number. 28 = 1 x 28, 2 x 14, or 4 x 7. Factors of 28: 1, 2, 4, 7, 14, 28. Prime factorization: 28 = 2 x 2 x 7, which can also be written 28 = 2² x 7.

Answer 2

Concept:

Prime factorization is a mathematical method to express a numerical entity or numerical value in terms of the product of their factors which are prime numbers.  

Prime numbers are those number which have 1 and itself only as factors.

Given:

Given numbers are 16,28,38

Find:

We have to find the prime factorization of 16, 28, 38.

Solution:

Given numbers are given by 16, 28, 38

Prime factorization of the number are given by,

16 = 2*2*2*2*1

28 = 2*2*7*1

38 = 2*19*1

So the prime factorization of the given numbers 16, 28, 38 are given by,

16 = 2*2*2*2*1

28 = 2*2*7*1

38 = 2*19*1
