Decompose 84. The prime factor is______ ．

To decompose a prime factor is to write a composite number into the continuous product of several prime numbers. Using the short division method, we can decompose it from the smallest prime number 2, which can be decomposed into: 84 = 2 × 2 × 3 × 7. So the answer is: 84 = 2 × 2 × 3 × 7
