A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 59 does not have any factors besides 1 and itself (not more than two factors), so it is a prime number.
210 has 4, which is the maximum possible. There are other numbers with 4 different prime factors.
To find the least common denominator of 143 and 208, we need to first find the prime factors of each number. The prime factors of 143 are 11 and 13, while the prime factors of 208 are 2, 2, 2, 2, 13. The least common denominator is the product of all the prime factors with the highest power present in either number, which is 2^4 * 11 * 13 = 1144. Therefore, the least common denominator of 143 and 208 is 1144.
