Question

2. Find the HCF of 16 and 40 by listing factors​

Answer 1

Answer:

8

Step-by-step explanation:

16 divided by 8 is 2. 40 divided by 8 is 5. Neither of these can be reduced by any more common numbers, so therefore, 8 is your greatest common factor. The GCF of 16 and 40 is 8.

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

• 16 = 2 × 2 × 2 × 2

• 40 = 2 × 2 × 2 × 5

• HCF(16,40) = 2 × 2 × 2 = 8
