Is 19 a composite or prime factor
5 x 7 = 35
Since 160 is a composite number, it would be a composite factor.
160 80,2 40,2,2 20,2,2,2 10,2,2,2,2 5,2,2,2,2,2
The prime factors of 160 are 2, 2, 2, 2, 2, and 5. The prime factors of 195 are 3, 5, and 13. The prime factors they have in common are a single 5, so 5 is the greatest common factor.
A positive integer greater than one must be either prime or composite. It cannot be neither. 2 divides 160. That is, 160 has a factor other than 1 and itself. So it is not a prime and therefore is composite.
2 x 2 x 2 x 2 x 2 x 5 = 160
160 is a composite no. and 19 is a prime no.
2 x 2 x 2 x 2 x 2 x 5

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.
