Take the number 244 and divid it by the smalled prime number that you can get and below is a list of prime numbers and the prime number that you use must not leave any remainder.

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271 ...

244 / 2 = 122
122 / 2 = 61
61 / 2 gives us a remainder so we can not use that one
61 / 3 also gives us a remainder but look at the list of prime numbers 61 is a prime number as well so
61 / 61 = 1

Then your final answer is

= 2 x 2 x 61
= 2^2 x 61

(16*18)^2 = (2^2 * 3* 5)^2 (mod 244)
(44)^2 = (60)^2 (mod 244)

(244, 16) = 2(122, 8) = 2(2) = 4

So 4 I 244 and 244 factors out as 2^2 *61

Using Prime Factor Method we get
244 = 2 * 2 * 61
or
244 = 2^2 * 61

244/2=122 first is 2
122/2=61 second is 2
61 is prime for itself
So the answer is 2×2×61
I hope that you understand this and good luck!

4 x 61

2 ² x 61

244 = 2 x 2 x 61
or
244 = 2^2 x 61
