2 x 2 x 3 x 5 x 7 = 420
To find the highest prime factor of 420, we first need to factorize 420 into its prime factors. 420 can be expressed as 2^2 * 3 * 5 * 7. The highest prime factor is 7. Prime factors are numbers that can only be divided by 1 and themselves without leaving a remainder, and the highest prime factor is the largest prime number that can divide the original number.
420 = 22 x 3 x 5 x 7
Find one factor, divide by it to get the other factor. Continue separating each of the factors into smaller factors, until you only have prime numbers. For example, 840 = 2 x 420. Now continue finding smaller factors for 420.
420 has four prime factors: 2,3,5,7
The prime factors of 420 are: 2, 3, 5, 72 x 2 x 3 x 5 x 7 = 420
