WebThe number 20 is a composite number because it is divisible at list by 2 and 5. See below how many and what are their divisors. The prime factorization of the number 20 is written ,as product of powers, as 2 2 •5 .. The prime factors of 20 are 2 and 5.. Prime factors do not always represent all divisors of a number.The number 20 has the folowing divisors or … WebAnswer (1 of 2): The prime factorization of 7200 is (2^5)(3^2)(5^2). Hence the number of positive divisors of 7200, denoted by tau(7200)=(5+1)(2+1)(2+1) = 54. Note that the number of divisors only depends on the exponents on the prime divisors, and not on the primes themselves. The above formul...

Also, we may assume that we have the smallest primes, i.e., n = 2 e 1 3 e 2 5 e 3 7 e 4 . So your method works well, and we obtain, after only cheking a few cases, d ( 1680) = d ( 2 4 ⋅ 3 ⋅ 5 ⋅ 7) = 5 ⋅ 2 ⋅ 2 ⋅ 2 = 40 as the maximum. little big town tour uk

WebApr 5, 2024 · So the number of non-trivial divisors will be 2 less than the total divisors of a number. We will find the non-trivial divisors of 2160: 40 − 2 = 38. We have calculated that the total number of non-trivial divisors of 2160 is 38. ∴ Option C is the correct option. Note: We can also count the non-trivial divisors by listing out all the ...
