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
The greatest common factor can be calculated by identifying the common prime factors and multiplying them together. The prime factors of 280 are 2, 2, 2, 5, and 7. The prime factors of 420 are 2, 2, 3, 5, and 7. The common prime factors are 2, 2, 5, and 7, so the greatest common factor is 2 x 2 x 5 x 7 = 140. The GCF is 140.
There are 82 prime numbers between 1 and 420.
To express 375 in prime factor index form, first, factor it into its prime components. The prime factorization of 375 is (3 \times 5^3) because (375 = 3 \times 125) and (125 = 5^3). Therefore, the prime factor index form of 375 is (3^1 \times 5^3).
420 has 5 prime factors, four of which are different prime numbers. Prime factors of 420 are 2 x 2 x 5 x 3 x 7.
Exactly as it is because 31 is a prime number
420 has four prime factors. Prime factors don't usually travel in pairs.
To find the greatest common factor (GCF) of 180, 450, and 420, we first need to find the prime factorization of each number. The prime factorization of 180 is 2^2 x 3^2 x 5, the prime factorization of 450 is 2 x 3^2 x 5^2, and the prime factorization of 420 is 2^2 x 3 x 5 x 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 2^2 x 3 = 12. Therefore, the greatest common factor of 180, 450, and 420 is 12.
