Question

find the HCF of 225, 450 by division method​

Answer 1

Answer:

Find the prime factorization of 225. 225 = 3 × 3 × 5 × 5.

Find the prime factorization of 450. 450 = 2 × 3 × 3 × 5 × 5.

To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 3 × 3 × 5 × 5.

GCF = 225.

$\tt255 = 3 \times 3 \times 5 \times 5$

$\tt450 = 2 \times 3 \times 3 \times 5 \times 5$

$\tt{hcf = 3 \times 3 \times 5 \times 5 = 255}$
