Which is the greatest common factor 50 or 120?
The prime factorization of 50 is 2 x 5 x 5 = 50. The prime factorization of 120 is 2 x 2 x 2 x 3 x 5 = 120. The occurrences of common prime factors of 20, 50 and 120 are 2 and 5. So the greatest common factor of 20, 50 and 120 is 2 x 5 = 10.
Which is the greatest common factor of 20 and 10?
Now let’s find the GCF of our third value, 20, and our result, 10. GCF (20,10) So, the greatest common factor of 20 and 10 is 10. Therefore, the greatest common factor of 120, 50 and 20 is 10. So, the the greatest common factor of 182664 and 154875 is 177. So, the greatest common factor of 177 and 137688 is 3.
How do you calculate the greatest common factor?
Given two whole numbers, subtract the smaller number from the larger number and note the result. Repeat the process subtracting the smaller number from the result until the result is smaller than the original small number. Use the original small number as the new larger number. Subtract the result from Step 2 from the new larger number.
Which is the prime factorization of 20 and 50?
The prime factorization of 20 is 2 x 2 x 5 = 20. The prime factorization of 50 is 2 x 5 x 5 = 50. The prime factorization of 120 is 2 x 2 x 2 x 3 x 5 = 120. The occurrences of common prime factors of 20, 50 and 120 are 2 and 5.
