95 = 5 * 19 both of which are prime, so 95 has 4 divisors as does any number that is the product of 2 primes. The divisors are 1,5,19 and 95.
The smallest number with exactly 14 divisors is 192. The divisors are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, and 192 itself.
Amicable numbers are pairs of numbers for which the sum of the proper divisors (the divisors except for the number itself) equals the other number in the pair. The smallest amicable pair is 220 and 284. The proper divisors of 220 are and the factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, and 110, the sum of which is 284. The proper divisors of 284 are 1, 2, 4, 71, and 142, the sum of which is 220.
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.
Divisors are used to divide numbers.
The first number to have exactly 10 divisors is 48.
Divisors are whole numbers. The divisors of 100 between 1 and 10 are 1, 2, 4, 5 and 10.
The divisors of 10 are 1, 2, 5, and 10.
