Question

EXERCISE 3.6
Find the HCF of the following numbers
() 18,48 (b) 30,42
(e36.84 (0) 34, 102
h) 91, 112, 490 18.54.81
5. What is the HF of two consecutive
munen? (b) even numbers?
​

Answer 1

Step-by-step explanation:

For taking hcf

first prime factorise the no.s

eg: 18 = 1×2×3×3

then check which factors of them are same.

eg:

18 = 1×2×3×3

48 = 1×2×2×2×2×3

here 1×2×3 are common then hcf = 6

Answer 2

6 is the answer do prime factorisation
