How do you find the factorization of the number 75?
Prime factorization: It is a method to express each number as the product of prime numbers.Step 1: Which prime number divide 75?Ans: 3 and 5.But, we should start with the smallest prime number which divides 75.75÷3 = 25Step 2: Which prime number divide 25?Ans: 525÷5 = 5Step 3: We have to continuously divide each quotient by a prime number until the quotient itself is a prime number.In step 2 we are left with 5(prime number) as a quotient.So, prime factorization of 75 = product of all the quotients = 3x5x5

Is 887 a prime number?
Yes, 887 is a prime number. Recall that if a number is not prime then there exists a prime less than the square root of the number and this prime divides the number. So we need to check if the primes less than 30 divides 887 or not. These primes are 2,3,5,7,11,13,17,19,23,29.
Algorithm to find whether a number is prime or not?
check if 2 divides the Numbercheck if 3 divides the Numbercheck if 5 divides the Number...check if any prime numbers less than the square root of the Number divide the NumberIf any do, the Number is composite; otherwise the Number is prime.This is called the Sieve of Erasthenes.An easy way to check if a prime number divides the Number in base ten (if you don't have a calculator) is to add or subtract 1 or 3 times the prime number to the Number, so that the sum or difference is a multiple of ten (if the prime number isn't 2 or 5). Knock off the zero. If the prime number divides the new number, it also divides the Number; otherwise it doesn't.
