The last prime before 400 is 397.The prime factorization of 400 is 2x2x2x2x5x5.
The Highest Common Factor (HCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the HCF of 120 and 400, you can use the prime factorization method. The prime factorization of 120 is 2^3 * 3 * 5 and the prime factorization of 400 is 2^4 * 5^2. To find the HCF, you take the common prime factors with the lowest exponent, which in this case is 2^3 * 5 = 40. Therefore, the HCF of 120 and 400 is 40.
The questioner might have meant to ask, "What are the prime factors of 400?" If this was the question, the answer is 2 and 5. More often, that locution is used in place of, "What is the prime factorization of 400?" If that was the question, the answer is 2 x 2 x 2 x 2 x 5 x 5.
