Question

Find the HCF of factorisation method of 345 and 726 and 531

Answer 1

Answer:

HCF Highest common multiple Gcf greatest common multiple

Step-by-step explanation:

Find the prime factorization of 1233

1233 = 3 × 3 × 137

Find the prime factorization of 726

726 = 2 × 3 × 11 × 11

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

Therefore, GCF = 3

Find the prime factorization of 343

343 = 7 × 7 × 7

Find the prime factorization of 531

531 = 3 × 3 × 59

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

Therefore, GCF = 1
