Answer 2

Answer:

2

Step-by-step explanation:

First we will find the common factors of 10. The common factors of 10 are 1, 2, 5 and 10. 1, 2, 5 and 10 are common factors of 10 because they will divide into 10. Now, we'll find common factors of 16. The common factors of 16 are 1, 2, 4, 8 and 16. 1, 2, 4, 8 and 16 are common factors of 16 because they will divide into 16. Now we will find the HCF between them. the common factors are 1 and 2. but, between 1 and 2, The highest common factor is 2. Hence, the answer is 2.
