Question

find hcf of 455 and 42 using euclids division lemma

Answer 1

according to euclid division lemma 

455=42*10+35
42=35*1+7
35=7*5+0

since remainder become zero at divisor 7 so 7 is hcf of 455 and 42

Answer 2

Answer: 7

Step-by-step explanation:

We have,455>42

Using Euclid's Division Lemma/Algorithm,

455=42×10+35

Again, 42=35×1+7

Again, 35=7×5+0

Therefore, the last divisor 7 is the HCF.
