10,677,792 and 60,466,176 are not relatively prime... if:
- If there is at least one number other than 1 that evenly divides the two numbers (without a remainder). Or...
- Or, in other words, if their greatest (highest) common factor (divisor), gcf (hcf, gcd), is not equal to 1.
Calculate the greatest (highest) common factor (divisor),
gcf (hcf, gcd), of the two numbers
Method 1. The prime factorization:
The prime factorization of a number: finding the prime numbers that multiply together to make that number.
10,677,792 = 25 × 3 × 111,227
10,677,792 is not a prime number, is a composite one.
60,466,176 = 210 × 310
60,466,176 is not a prime number, is a composite one.
- Prime number: a number that is divisible (dividing evenly) only by 1 and itself. A prime number has only two factors: 1 and itself.
- Composite number: 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) (10,677,792; 60,466,176) = 25 × 3 = 96 ≠ 1
Are the numbers 10,677,792 and 60,466,176 coprime (prime to each other, relatively prime)? No, they are not.

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:
60,466,176 ÷ 10,677,792 = 5 + 7,077,216
Step 2. Divide the smaller number by the above operation's remainder:
10,677,792 ÷ 7,077,216 = 1 + 3,600,576
Step 3. Divide the remainder of the step 1 by the remainder of the step 2:
7,077,216 ÷ 3,600,576 = 1 + 3,476,640
Step 4. Divide the remainder of the step 2 by the remainder of the step 3:
3,600,576 ÷ 3,476,640 = 1 + 123,936
Step 5. Divide the remainder of the step 3 by the remainder of the step 4:
3,476,640 ÷ 123,936 = 28 + 6,432
Step 6. Divide the remainder of the step 4 by the remainder of the step 5:
123,936 ÷ 6,432 = 19 + 1,728
Step 7. Divide the remainder of the step 5 by the remainder of the step 6:
6,432 ÷ 1,728 = 3 + 1,248
Step 8. Divide the remainder of the step 6 by the remainder of the step 7:
1,728 ÷ 1,248 = 1 + 480
Step 9. Divide the remainder of the step 7 by the remainder of the step 8:
1,248 ÷ 480 = 2 + 288
Step 10. Divide the remainder of the step 8 by the remainder of the step 9:
480 ÷ 288 = 1 + 192
Step 11. Divide the remainder of the step 9 by the remainder of the step 10:
288 ÷ 192 = 1 + 96
Step 12. Divide the remainder of the step 10 by the remainder of the step 11:
192 ÷ 96 = 2 + 0
At this step, the remainder is zero, so we stop:
96 is the number we were looking for - the last non-zero remainder.
This is the greatest (highest) common factor (divisor).
