To find the prime factorization of 420, we start by dividing it by the smallest prime number, which is 2.
420 ÷ 2 = 210
Since 210 is divisible by 2, we continue dividing:
210 ÷ 2 = 105
Again, we divide by 2:
105 ÷ 3 = 35
Now, we divide by 5:
35 ÷ 5 = 7
7 is a prime number, so we stop.
Therefore, the prime factorization of 420 is:
2 × 2 × 3 × 5 × 7
Written in multiplication form: 2^2 × 3 × 5 × 7
420 ÷ 2 = 210
