Answer:
[tex]1764 = 2^2 \times 3^2 \times 7^2[/tex]
Step-by-step explanation:
Divide by the prime numbers in increasing order until you find all the prime factors.
The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17
1764/2 = 882
882/2 = 441
441/3 = 147
147/3 = 49
49/7 = 7
7/7 = 1
[tex]1764 = 2^2 \times 3^2 \times 7^2[/tex]
