Answer 1

Answer:

Highest common factor (HCF) of 480, 720 is 240.

Step-by-step explanation:

Find the prime factorization of 480

480 = 2 × 2 × 2 × 2 × 2 × 3 × 5

Find the prime factorization of 720

720 = 2 × 2 × 2 × 2 × 3 × 3 × 5

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

Therefore, GCF = 2 × 2 × 2 × 2 × 3 × 5

GCF = 240
