What is the prime factorization of 40 and 60 with exponents?
40 = 23 x 51 60 = 22 x 31 x 51
The prime factorization to 40 is 2x2x2x5?
Yes, the prime factorization of 40 is 2 x 2 x 2 x 5
What is the hcf of 160 and 200?
The highest common factor (HCF) of 160 and 200 is the largest positive integer that divides both 160 and 200 without leaving a remainder. To find the HCF, you can use the prime factorization method. The prime factorization of 160 is 2^5 * 5, and the prime factorization of 200 is 2^3 * 5^2. To find the HCF, you take the common factors with the lowest exponent, which in this case is 2^3 * 5 = 40. Therefore, the HCF of 160 and 200 is 40.
What is the least common multiple of 40 50 and 70?
To find the least common multiple (LCM) of 40, 50, and 70, we first need to find the prime factorization of each number. The prime factorization of 40 is 2^3 * 5, the prime factorization of 50 is 2 * 5^2, and the prime factorization of 70 is 2 * 5 * 7. To find the LCM, we take the highest power of each prime factor that appears in any of the numbers. Therefore, the LCM of 40, 50, and 70 is 2^3 * 5^2 * 7 = 1400.
