156 is a not a prime number. A prime number is a number that only can divided by 1 and itself. Examples of Primes is 1, 2,3, 5, 7, 11, 13, 17.......................... 156 factors include 1,2,3,4,6,12,13,26,39,52,78,156.

There is no quick way to work out if a number is prime or not, the only way is to see if it can be divided by any numbers that aren't itself or one.
There is no easy way or really, any way at all to memorize an infinite list.

A prime number is one that is only divisible by 1 and itself. Just work out if it divides into anything. To do this try dividing the number by all prime numbers under its half way value.
No. An easy way to see this is the last digit is 5. 5 divides this number.
There is no easy way or really, any way at all to memorize an infinite list.
lcm of 46 and 69 = 139 an easy way to figure this out is by multiplying together the following: prime factors they have in common * prime factors that just 46 has * prime factors just 69 has.

An easy way to find a number relatively prime to another number is to find a nearby prime number. For example, 53 is relatively prime with 50. The following pairs are relatively prime. 3, 50 19, 50 37, 50 49, 50 50, 69 50, 201 50, 341 Any number that is not divisible by 2 or 5 will be relatively prime to 50.

Easiest way to answer this question yourself is can this number be divided by 2 or 3 and not have a decimal or any "leftover" numbers? 999997 / 2 = 499998.5 = Nope 999997 / 3 = 333332.33 = Nope Answer: Yes, 999997 is a prime number. No, the above is not a legitimate prime test. 999997 is actually 757 * 1321 and is not prime. There is no easy prime test you can do in your head that I know of.
Check if a number is divisible by 2. Then check divisibility by all odd numbers, up to the square root of the number. If it isn't divisible by any of those, your number is a prime number. For higher numbers, this method may be very slow - but you asked for EASY methods, and the faster methods are certainly not easy.
when you are using megetron there is a easy way and a hard way to kill optimus prime the hard way is punch him and shoot him until he is dead the easy way is get optimus prime to follow you to the water then transform and fly above the water optimus prime will jump after you but he will fall into the water and he will be dead
