1, 2, and 3 are the first three positive integers, but you can't say that they're the first three positive numbers. If you try that, somebody is sure to come along and say "but what about 0.1, 0.2, and 0.3 ?"
The fact is, nobody can say what the first (lowest) positive 'number' is. Whatever number you name, no matter how small it is, there is always another one that's smaller and still positive.
product = 6 first three positive counting numbers = 1, 2, 3product of the first three positive counting numbers:1 x 2 x 3 = 6
The first ten positive numbers total 55.

By treating it as a positive number. Since negative numbers include the factors of their positive counterparts and all positive numbers are greater than all negative numbers, the GCF will always be positive. The GCFs of (3, 9), (3, -9), (-3, 9) and (-3, -9) are all the same: positive 3.
The first 10 positive odd numbers are 1, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
2, 3 and 5.
product = 6 first three positive counting numbers = 1, 2, 3product of the first three positive counting numbers:1 x 2 x 3 = 6
A set can be anything. {1, 2, 3} is a set of the first 3 counting numbers. It's also the first three positive integers. The the set of the smallest positive whole numbers.
1 2 3 4 5 6 and 7 are the first 7 positive #s
The first ten positive numbers total 55.
The sum of the first 30 positive even numbers is 930.
The sum of the first 100 positive even numbers is 10,100.
It is: 2*3*5*7 = 210
1, 3, 5, 7, 9, 11
The sum of the first 1,000,000 positive even numbers is: 2 + 4 + 6 + 8 + ... + 2,000,000 The sum of the first 1,000,000 positive odd integers is: 1 + 3 + 5 + 7 + ... + 1,999,999 The difference between the two is: (2-1) + (4-3) + (6-5) + (8-7) + ... + (2,000,000-1,999,999). This is the same as: 1 + 1 + 1 + 1 + ... + 1. Well how many 1's are there? 1,000,000. So the difference is 1,000,000. Note that if the question asked for the difference between the sum of the first 1,000 positive even numbers and the sum of the first 1,000 positive odd numbers, the answer would be 1,000. The first n even numbers and odd numbers? n.
The sum of the first six positive numbers (1 to 6) is 21.
The sum of the first 30 positive even numbers is 930.
