Chat with our AI personalities
To find the highest common factor (HCF) of two numbers, we need to determine the largest number that divides both numbers without leaving a remainder. The prime factorization of 133 is 7 x 19 and the prime factorization of 203 is 7 x 29. The common factor between the two numbers is 7, making the highest common factor of 133 and 203 equal to 7.
Let's convert -4.06 to a fraction and check things out. We'll "separate" the number like this: -4.06 = -(4 + 0.06) = -(4/1 + 6/100). Now we have two fractions. Let's expand the first one so the denominators are equal and then we can add them. As 4/1 = 400/100, we can put that back in our expression. We have -(400/100 + 6/100) = -(406/100) = -(203/50). We divided both the numerator and denominator by 2 to get the last answer, and the 203 has no factors in common with 50, so the fraction will not reduce. The answer is - 203/50. In case you can't make that out, it's the fraction 203/50 with a negative sign in front of the "bar" of the fraction.
The first 10 multiples are: 203, 406, 609, 812, 1015, 1218, 1421, 1624, 1827, 2030 . . .
203
7 x 29 = 203, 7 x 71 = 497. There are therefore 71 - 28 ie 43 multiples of 7 in the range.
Oh, dude, a composite number is a number that has more than two factors, like 4, 6, or 12. So, if you want a chart of composite numbers between 1-1000, you'd basically be listing out all the numbers that aren't prime. That's like a lot of numbers, man. You might need a whole scroll for that one.
