Answer
$2^{2} \times 3 \times 5^{2} \times 7$
Work Step by Step
Divide 2100 by 2 until the result is no longer divisible by 2. The number of times you divided by 2 becomes the exponent for the factor 2.
$2^{2} \times 525$
To continue with the prime factorization, divide 525 by 3 until it is no longer divisible by 3. The number of times you divided by 3 becomes the exponent for the factor 3.
$2^{2} \times 3 \times 175$
To continue with the prime factorization, divide 175 by 5 until it is no longer divisible by 5. The number of times you divided by 5 becomes the exponent for the factor 5.
$2^{2} \times 3 \times 5^{2} \times 7$
