Question 256147
<font face="Garamond" size="+2">


875 is not even, so 2 is not a factor.


8 + 7 + 5 = 20.  2 + 0 = 2.  2 is not divisible by 3, so 875 is not divisible by 3.


875 ends in 5, so it is divisible by 5.  875/5 = 175.


175 ends in 5, so it is divisible by 5.  175/5 = 35.


35/5 = 7


The complete prime factorization of 875 is thus *[tex \LARGE 5^3\,\cdot\,7], and to answer your question precisely, 5 and 7.
