The HCF of 400 and 1000 is 200

Answer 2

Step-by-step explanation:

Steps to find GCF

Find the prime factorization of 400

400 = 2 × 2 × 2 × 2 × 5 × 5

Find the prime factorization of 1000

1000 = 2 × 2 × 2 × 5 × 5 × 5

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2 × 2 × 5 × 5

GCF = 200
