Question

2)Find HCF ,Using prim factorization method of 18,30 and 27 .​

Answer 1

Answer:

3

Step-by-step explanation:

18=2*3^2

30=2*3*5

27=3^3

common prim factorization is of 18, 30, 27 is 3

Answer 2

Given :- Find HCF ,Using prime factorization method of 18,30 and 27 .

Solution :-

finding prime factors of 18, 30 and 27 first,

→ 18 = 2 * 3 * 3

→ 30 = 2 * 3 * 5

→ 27 = 3 * 3 * 3

since we know that, HCF is smallest number that divides all given numbers and as we can see that, only prime factor common in all three given numbers is 3 .

therefore, we can conclude that,

→ HCF(18, 30, 27) = 3 (Ans.)
