Question

2. Use division method to find the H.C.F. of the following numbers:
(a) 25 and 35 (b) 40 and 76 (c) 135 and 165
(d) 198 and 360 (e) 144 and 312 (f) 400 and 575
3. Show that 35 and 48 are coprime numbers.​

Answer 1

Answer:

2 a)1.4

b)4

c)15

d)18

e)24

f)25

3.35 , 48 are co-primes. factors of 35 = 1,5,7,35factors of 48 =1,2,3,4,6,8,12,16,24,48no common factorhence 35 , 48 are co-primes.

Step-by-step explanation:

We divide the bigger number by smaller one. Divide smaller number in step 1 with remainder obtained in step 1. Divide divisor of second step with remainder obtained in step 2. We will continue this process till we get remainder zero and divisor obtained in end is the required H.C.F.
