40/ \4*10/ \2*2 5*2Hope this helped you
All I did was make a factor tree. The GCF (Greatest Common Factor) is 5. :)
Two factors of 40 are 20 and 2. There are no more factors of 2, but factors of 20 include 5 and 4. There are no more factors of 5 but 4 factors of 4 include 2 and 2. So, the factors of 40 are 2, 5, 2, 2 This simplifies to make 2^3 * 5 Hope that helped :)
Keep dividing by two. 32 16,2 8,2,2 4,2,2,2 2,2,2,2,2 40 20,2 10,2,2 5,2,2,2

No. While 4 is a factor of 40, it is not a prime number.
