Are 5,886 and 8,841 coprime (prime to each other, relatively prime)?
5,886 and 8,841 are not relatively prime - if there is at least one number other than 1 that evenly divides the two numbers (without a remainder) - or, in other words - if their greatest (highest) common factor (divisor), gcf (hcf, gcd), is not 1.
Calculate the greatest (highest) common factor (divisor), gcf (hcf, gcd), of the numbers
Method 1. The prime factorization:
The prime factorization of a number: finding the prime numbers that multiply together to make that number.
5,886 = 2 × 33 × 109
5,886 is not a prime number, is a composite one.
8,841 = 3 × 7 × 421
8,841 is not a prime number, is a composite one.
The numbers that are only divisible by 1 and themselves are called prime numbers. A prime number has only two factors: 1 and itself.
A composite number is a natural number that has at least one other factor than 1 and itself.
Calculate the greatest (highest) common factor (divisor), gcf (hcf, gcd):
Multiply all the common prime factors of the two numbers, taken by their smallest exponents (powers).
gcf (hcf, gcd) (5,886; 8,841) = 3
Coprime numbers (prime to each other, relatively prime) (5,886; 8,841)? No.
The two numbers have common prime factors.
gcf (hcf, gcd) (5,886; 8,841) = 3
Method 2. The Euclidean Algorithm:
This algorithm involves the process of dividing numbers and calculating the remainders.
'a' and 'b' are the two natural numbers, 'a' >= 'b'.
Divide 'a' by 'b' and get the remainder of the operation, 'r'.
If 'r' = 0, STOP. 'b' = the gcf (hcf, gcd) of 'a' and 'b'.
Else: Replace ('a' by 'b') and ('b' by 'r'). Return to the step above.
Step 1. Divide the larger number by the smaller one:
8,841 ÷ 5,886 = 1 + 2,955
Step 2. Divide the smaller number by the above operation's remainder:
5,886 ÷ 2,955 = 1 + 2,931
Step 3. Divide the remainder of the step 1 by the remainder of the step 2:
2,955 ÷ 2,931 = 1 + 24
Step 4. Divide the remainder of the step 2 by the remainder of the step 3:
2,931 ÷ 24 = 122 + 3
Step 5. Divide the remainder of the step 3 by the remainder of the step 4:
24 ÷ 3 = 8 + 0
At this step, the remainder is zero, so we stop:
3 is the number we were looking for - the last non-zero remainder.
This is the greatest (highest) common factor (divisor).
gcf (hcf, gcd) (5,886; 8,841) = 3
