You can dispose a number 
of elements in a matrix-like formation with 
shape if and only if 
and 
both divide , and also 
.
So, we need to find the greatest common divisor between 
and 
, so that we can use that divisor as the number of columns, and then.
To do so, we need to find the prime factorization of the two numbers:
So, the two numbers share only one prime in their factorization, namely 
, but we can't take "too many" of them: has "three two's" inside, while has "five two's" inside. So, we can take at most "three two's" to make sure that it is a common divisor. As for the other primes, we can't include 
nor 
, because it's not a shared prime.
So, the greater number of columns is 
, which yield the following formations:
