Are 8,934 and 7,197,120 coprime (prime to each other, relatively prime)?
8,934 and 7,197,120 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.
8,934 = 2 × 3 × 1,489
8,934 is not a prime number, is a composite one.
7,197,120 = 26 × 33 × 5 × 72 × 17
7,197,120 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) (8,934; 7,197,120) = 2 × 3 = 6
Coprime numbers (prime to each other, relatively prime) (8,934; 7,197,120)? No.
The two numbers have common prime factors.
gcf (hcf, gcd) (8,934; 7,197,120) = 6
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:
7,197,120 ÷ 8,934 = 805 + 5,250
Step 2. Divide the smaller number by the above operation's remainder:
8,934 ÷ 5,250 = 1 + 3,684
Step 3. Divide the remainder of the step 1 by the remainder of the step 2:
5,250 ÷ 3,684 = 1 + 1,566
Step 4. Divide the remainder of the step 2 by the remainder of the step 3:
3,684 ÷ 1,566 = 2 + 552
Step 5. Divide the remainder of the step 3 by the remainder of the step 4:
1,566 ÷ 552 = 2 + 462
Step 6. Divide the remainder of the step 4 by the remainder of the step 5:
552 ÷ 462 = 1 + 90
Step 7. Divide the remainder of the step 5 by the remainder of the step 6:
462 ÷ 90 = 5 + 12
Step 8. Divide the remainder of the step 6 by the remainder of the step 7:
90 ÷ 12 = 7 + 6
Step 9. Divide the remainder of the step 7 by the remainder of the step 8:
12 ÷ 6 = 2 + 0
At this step, the remainder is zero, so we stop:
6 is the number we were looking for - the last non-zero remainder.
This is the greatest (highest) common factor (divisor).
gcf (hcf, gcd) (8,934; 7,197,120) = 6
Coprime numbers (prime to each other, relatively prime) (8,934; 7,197,120)? No.
