Question

36,420 and 90 what is the HCF of this​

Answer 1

Step-by-step explanation:

step 1

Here 36 is greater than 24

we apply the division lemma to 36 and 24, to get

36 = 24 x 1 + 12

step 2

Since the reminder 24 ≠ 0, we apply division lemma to 12 and 24, to get

24 = 12 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 24 and 36 is 12

step 3

Here 420 is greater than 12

Now, consider the largest number as 'a' from the given number ie., 420 and 12 satisfy Euclid's division lemma statement a = bq + r where 0 ≤ r < b

Step 1: Since 420 > 12, we apply the division lemma to 420 and 12, to get

420 = 12 x 35 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 420 is 12

Notice that 12 = HCF(420,12) .

Therefore, HCF of 24,36,420 using Euclid's division lemma is 12.
