Why do most numbers have even and some odd factors?

Answer 1

If a number ends in 0, 2, 4, 6, or 8, it is an even number. The following numbers are even numbers:

1,368,054

7,999,000

4,871,532

13,656,738

335,791,594

58,909,257,019,770

871,542,001,854,337,089,111,016

If one of the factors of a number is even, it is an even number. The following numbers are even numbers:

28 x 32 x 59

2 x 712 x 197

211 x 43 x 475

22 x 32 x 53 x 710 x 112 x 234

A number that ends in 1, 3, 5, 7, or 9 is an odd number. A number that does not have an even factor is an odd number. A number that is 1 less than an even number is an odd number. The following numbers are odd numbers, not even numbers:

176,999,711

37 x 112 x 132 x 174 x 196

2125 - 1

Answer 2

That's simply not true. The only numbers that have at least one even factor are the even numbers (those that end in 2, 4, 6, 8, 0). That's only half of the numbers - not what I would call "most numbers".
