Two. The 5 and 7 are odd numbers. The 2 is an even number.
In any range of numbers, the number of evens and odds can never be different by more than 1 . If you include the 572 and the 592, then that range includes 11 evens and 10 odds.
The only even prime is 2, so neither 234 nor 788 is prime. Since 1+2+3=6 is divisible by 3, the divisibility test for 3 says 123 can not be prime. If one of the options must be prime, then we know it is 563. Just to check:563 is odd and not divisible by 3,5,7,11,13,17,19, or 23. Since it is not divisible by any primes less than its square root, we know that 563 is not divisible by any whole numbers other than itself and one and is hence prime.
27 is an odd number.
An odd number minus an odd number is an even number.
when an odd number is subtracted from an odd number the answer is an even number.
Every number that has an odd number must be a number that has a whole number as a squareroot...for example 25:25 1, 5, 254 1, 2, 49 1, 3, 916 1, 2, 4, 8, 1636 1, 2, 3, 4, 6, 9, 12, 18, 3649 1, 7, 49If you notice, the squareroot, is always in the very center of the factors. And If you multiply the number right before, and the number right after, and the numbers following those, you always get the number you started with.Numbers that do not have a whole number as a squareroot will not have an odd number of factors. The odd number is always the center number, which, if multiplied times itself gives you your answer.
