200 × 100 ÷ 230 = 86.95%
690 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, and 690.The factor pairs of 690 are 1 x 690, 2 x 345, 3 x 230, 5 x 138, 6 x 115, 10 x 69, 15 x 46, and 23 x 30.The proper factors of 690 are 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, and 345 or,if the definition you are using excludes 1, they are 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, and 345.The prime factors of 690 are 2, 3, 5, and 23.The 4 distinct prime factors (listing each prime factor only once) of 690 are 2, 3, 5, and 23.The prime factorization of 690 is 2 x 3 x 5 x 23.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
1, 2, 5, 10, 23, 46, 115, 230
230 / 2 = 115 115 / 5 = 23 so the prime fact. is 2 x 5 x 23
The GCF is 115.
2
The GCF is 46.
The GCF is 10.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 69 and 230 is 23
230
The greatest common factor (GCF) of 2990 and 1150 is 230.
The common factors of 230 and 345 are 1, 5, 23, and 115
The GCF of 137 and 230 is 1. 137 is prime, and so its only factors are 1 and 137. Since 137 is not a factor of 230, the GCF of 137 and 230 is 1.
The common factors are: 1, 5, 23, 115
115, 230, 345 and so on.
You can simplify the term by approximation! Here is the approach: Let y = √x = x^(½). Then, dy/dx = ½ * x^(-½) = 1/(2√x) Select 115² to be x. Then, we obtain: y = 115 dy/dx = 1/(2 * 115) = 1 / 230 Therefore, we obtain this equation: y - 115 = 1/230 * (x - 115²) If x = 13144, then we have: y - 115 = 1/230 * (13144 - 115²) y = 1/230 * (13144 - 115²) + 115 ≈ 114.65 OR What you can do is to factor out each term by term and extract the perfect square factor out of the √. For instance: √(13144) = √(4 * 3286) = 2√3286
