The first number to have exactly 10 divisors is 48.

The only numbers which divide into 89 exactly are 1 and 89. These are called factors or divisors. Any number which has exactly 2 divisors (1 and the number itself) is a prime number.

Most certainly not. A prime is a number that has exactly two divisors: 1 and itself. Example: 2 is a prime. 4 is not; its divisors are: 1, 2 and 4.

A prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.

1,999,998 has exactly 1,000,000 divisors starting with 1, 2, 4, 6, 8,...up to 1,999,998.

There is only 1 value of N that satisfies 2029 x N has exactly three divisors: N = 2029 To have exactly three divisors, the number must be the square of a prime number. 2029 is a prime number with exactly 2 divisors (1 and 2029). Thus the only number with exactly three divisors of which two are 1 and 2029 is 20292 (= 4116841), making N = 2029.
