Question

1. Find the HCF of
(a) 18,48
(e) 36,84
(h) 91, 112, 49​

Answer 1

Answer:

(a) sol. 18,48

factors of 18 are

2*3*3

similarly the factors of 48 are

2*2*2*2*3

last, the common difference of these two factors

are

2and 3

Therefore the hcf of 18,48 is 2*3 is 6

Answer 2

Step-by-step explanation:

1 The highest common factor of 18 and 48 is simple. You should first find all the factors of each number.

Factors of 18 are: 1,2,3,6,9,18.

Factors of 48 are: 1,2,3,4,6,8,12,16,24,48

After that, you should find all the common factors between them.

Common factors are 1,2,3,6.

This means that your highest common factor should be 6 as it is the biggest factor that divides into both numbers.

Explanation:

2 .36 = 22 x 32
