Question

Watch help video What is the greatest common factor of 30,50 , and 10 ?

Answer 1

10

Step-by-step explanation:

30 = 2 * 3 * 5

50 = 2*5^2

10 = 2*5

so greatest common factor will be 2*5 = 10

Answer 2

To find the greatest common factor (GCF) of 30, 50, and 10, list the factors of each number and identify the largest common factor, which is 10.

Step-by-step explanation:

The greatest common factor (GCF) of numbers is the largest number that evenly divides all of them. To find the GCF of 30, 50, and 10, we can first list the factors of each number.

• Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
• Factors of 50: 1, 2, 5, 10, 25, 50
• Factors of 10: 1, 2, 5, 10

Looking at the lists, we can see the common factors of 30, 50, and 10 are 1, 2, 5, and 10. The largest of these common factors is 10. Therefore, the greatest common factor of 30, 50, and 10 is 10.
