Question

What are the common factors of 841 and 560​

Answer 1

Answer:

Calculate the greatest (highest) common factor (divisor), gcf (gcd):

Notice that dividing our numbers leaves no remainder:

560 ÷ 280 = 2 + 0;

560 is divisible by 280.

Consequently, greatest (highest) common factor (divisor):

gcf, gcd (280; 560) = 280 = 23 × 5 × 7;

Calculate the greatest (highest) common factor (divisor), gcf (gcd)

All common and prime factors (divisors) of the numbers 280 and 560?

Find all the factors (divisors) of the GCF (GCD), 280.

Take each of the GCF's prime factors, and their exponents, if there are, and all their combinations.

Also add 1 to the list of factors (divisors). Any number is divisible by 1.

280 and 560 have 16 common factors (divisors), out of which 3 prime factors, 2; 5 and 7:

Answer 2

Answer:

1

Step-by-step explanation:

Let's first list up all the factors of 841,

1, 29, 841

Now, also list up all the factors of 560,

1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

Now, let's find the common factors between both the lists given above,

Common Factors = 1

We see that only 1 is common between both.

Hence, the only common factor between 841 and 560 is 1.
