Find the greatest common factor of the following monoimals 46m^4 and 22m^3

For this case we have the following monomials:
 46m ^ 4
 22m ^ 3
 We can rewrite the monomials by doing common factor.
 We have entoces:
 The factors of 22 are: 1, 2, 11, 22
 The factors of 46 are: 1, 2, 23, 46
 The factors of m ^ 4 are: m, m ^ 2, m ^ 3, m ^ 4 
 The factors of m ^ 3 are: m, m ^ 2, m ^ 3
 Then the greatest common factor is 2m ^ 3.
 
 The greatest common factor of the following monoimals 46m ^ 4 and 22m ^ 3 is:
 2m ^ 3
