The lowest prime number is two, because it is the smallest integer that divides by 1 and by itself and not by a third integer. You see, a prime number is a number that only has two factors, one and itself. Many people think one is the smallest prime number but no it isn't. It only has one factor not two factors so it is a perfect number. a prime has exactly two factors.

62 is not a prime number and you cannot get a relitavely prime number it either is a prime number or it isnt a prime number!

No other number 62 can be divided by 2 as well as itself and 1 so NO IT IS NOT A PRIME NUMBER even numbers tend not to be prime numbers because they can be divided by two the only even number that is prime is 2 because it can only be divided by itself and 1 I hope this helped!

How do you express a number as a product of prime factors?

Divide the number by it's lowest prime factor possible continuosly until you get a one. The numbers will then be the prime factors. For example: Take the number 66. 2 is the smallest prime number and it is a factor of 64. So 66/2 = 33. 33 is not divisible by 2 so we take the next lowest prime factor: 33/3 = 11. 11 is divisible by nothing but itself and so 11 is the next lowest prime factor (remember we always need the answer to remain an integer): 11/11 = 1. Therefore 66 = 2 x 3 x 11.
