Question

Find the HCF of the following set of the numbers by prime factorization method A 304,180 b 225,375

Answer 1

Answer:

HCF(304,180)= 4

HCF (225,375) = 75

Step-by-step explanation:

A 304,180

304 = 2×2×2×2×19

= 2⁴×19

180 = 2×2×3×3×5

= 2²×3²×5

So,the HCF(304,180) = 2²

= 4

B 225,375

225 = 3×3×5×5

= 3²×5²

375 = 3×5×5×5

= 3×5³

So,the HCF (225,375) = 3×5²

= 75
