Question

Quizplus · Accepted Answer

To factor 70 into prime factors, we start by dividing by the smallest prime number, 2. We find that $70=2\cdot 35$. From there, we can see that 35 is not divisible by 2, but it is divisible by 5, another prime number. Therefore, we divide 35 by 5 to get $70=2\cdot5\cdot7$. So the prime factorization of 70 is $2 \cdot 5 \cdot 7$, which corresponds to choice letter C.
