Answer 1

Answer:

Find the prime factorization of 375

375 = 3 × 5 × 5 × 5

Find the prime factorization of 875

Answer 2

Answer:125

Step-by-step explanation:

3 I 375              

5 I 125

5 I 25

5 I 5

     1

5 I 625

5 I 125

5 I 25

5 I 5

     1

5 I 875

5 I 175

5 I 35

7 I 7

     1

So from the divisions above we can identify the prime factors of the following as,

375 = 3 x 5 x 5 x 5

625 = 5 x 5 x 5 x 5

875 = 5 x 5 x 5 x 7

So, H.C.F = 5 x 5 x 5

               =125
