PF of 190 = 2 x 5 x 19
181 and 191 are prime. Everything in between is composite.
No. It is an even number (bigger than 2). Which means it divisible by 2 so is not prime.
181
No.
190 is not prime
The prime factorisation is: 190 = 2519.
19x5x2
2 x 5 x 19 = 190
A famous theorem says that each number has a unique prime factorization.You can begin by expanding the number to known products, say 10 * 19 (or 5*38 or ...)You just keep going until only prime numbers remain. Here, 19 is prime but 10 is composite so we reduce it further to 2*5. Both of these are prime numbers, so we are done.The resulting pf is 190=2*5*19 (only powers of prime numbers on the right)It is: 2*5*19 = 190
PF of 190 = 2 x 5 x 19
190 = 21 x 51 x 191
