Question

EXERCISE 1.1
Use Euclid's division algorithm to find the HCF of
(a) 135 and 225
(b) 196 and 36220
(c) 867 and 255​

Answer 1

Answer:

a. 45

b. 8

c. 51

Step-by-step explanation:

Euclid's division algorithm is a=bq+r

a. 225=135×1+90

135=90×1+45

90=45×2+0

Therefore HCF=45

b. 36220=196×184+156

196=156×1+40

156=40×3+16

40=16×2+8

16=8×2+0

therefore hcf=8

c. 867=255×102

255=102×2+51

102=51×2+0

therefore hcf=51
