(i) 2730 (ii) 860

Answer 1

i) prime factorization calculator of 2730

Positive Integer factors of 2730 = 2, 3, 6, 5, 30, 7, 210, 13, 2730 divided by 2, 3, 5, 7, 13, gives no remainder.

ii) 860 is a composite number. The exponents in the prime factorization are 2, 1, and 1. Adding one to each and multiplying we get (2 + 1)(1 + 1)(1 + 1) = 3 × 2 × 2 = 12. Therefore 860 has exactly 12 factors.

Answer 2

Answer:

Step-by-step explanation:

1- The orange divisor(s) above are the prime factors of the number 2,730. If we put all of it together we have the factors 2 x 3 x 5 x 7 x 13 = 2,730. It can also be written in exponential form as 21 x 31 x 51 x 71 x 131.

2- 860 is a composite number.

Prime factorization: 860 = 2 × 2 × 5 × 43, which can be written 860 = 2² × 5 × 43.

The exponents in the prime factorization are 2, 1, and 1. ...

Factors of 860: 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860.
