HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 492, 3421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 492, 3421 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 492, 3421 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 492, 3421 is 1.

HCF(492, 3421) = 1

Highest Common Factor of 492,3421 using Euclid's algorithm

Highest Common Factor of 492,3421 is 1

Step 1: Since 3421 > 492, we apply the division lemma to 3421 and 492, to get

3421 = 492 x 6 + 469

Step 2: Since the reminder 492 ≠ 0, we apply division lemma to 469 and 492, to get

492 = 469 x 1 + 23

Step 3: We consider the new divisor 469 and the new remainder 23, and apply the division lemma to get

469 = 23 x 20 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 492 and 3421 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(469,23) = HCF(492,469) = HCF(3421,492) .
