well i dont now
the minerals its contains and their resistance to weathering
7 of them leaving 3 remaining
To find the highest prime factor of 420, we first need to factorize 420 into its prime factors. 420 can be expressed as 2^2 * 3 * 5 * 7. The highest prime factor is 7. Prime factors are numbers that can only be divided by 1 and themselves without leaving a remainder, and the highest prime factor is the largest prime number that can divide the original number.
Erosion is the main factor responsible for the oldest rock remaining at the highest elevations in New York. Over long periods of time, the forces of erosion have removed younger layers of rock, leaving behind the oldest, more resistant rocks at higher elevations. These rocks are able to withstand the erosion processes that have shaped the landscape over millions of years.
Oh, dude, the highest common factor of 85 and 155 is 5. It's like the biggest number that can divide both 85 and 155 without leaving a remainder. So yeah, 5 is the winner here.
To find the highest common factor (HCF) of 245 and 140, we need to determine the largest number that divides both 245 and 140 without leaving a remainder. The factors of 245 are 1, 5, 7, 35, 49, and 245. The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, and 140. The common factors of 245 and 140 are 1, 5, and 35. Therefore, the highest common factor of 245 and 140 is 35.
The highest common factor (HCF) of 10 and 25 is 5. This is because 5 is the largest positive integer that divides both 10 and 25 without leaving a remainder. The factors of 10 are 1, 2, 5, and 10, while the factors of 25 are 1, 5, 25. The highest common factor is the greatest number that appears in both lists, which in this case is 5.
The highest common factor of 28 and 49 is 7. This is because 7 is the largest number that can evenly divide both 28 and 49 without leaving a remainder. To find the highest common factor, you can list out the factors of each number and identify the largest number that appears in both lists.
The common factors of 35 and 91 are 1 and 7.
They are the numbers divisible into it and leaving no remainders.
The factors of 64 are 2, 2, 2, 2, 2, 2 (or 26.)The factors of 88 are 2, 2, 2, 11 (or 23, 11.)Therefore, the hcf would be 8 (23.)If this was a fraction problem of:64--- to simplify you would divide the fraction by 8/8, leaving you with 8/11 as your answer.88Obviously, 8 and 11 have no common factors remaining once this has been done.
The highest common factor (HCF) of 40 and 72 is the largest number that divides both 40 and 72 without leaving a remainder. To find the HCF, we need to identify the common factors of 40 and 72, which are 1, 2, 4, and 8. The highest common factor of 40 and 72 is 8.
