HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 824, 498, 20 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 824, 498, 20 is 2 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 824, 498, 20 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 824, 498, 20 is 2.

HCF(824, 498, 20) = 2

Highest common factor (HCF) of 824, 498, 20 is 2.

Highest Common Factor of 824,498,20 using Euclid's algorithm

Highest Common Factor of 824,498,20 is 2

Step 1: Since 824 > 498, we apply the division lemma to 824 and 498, to get

824 = 498 x 1 + 326

Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 326 and 498, to get

498 = 326 x 1 + 172

Step 3: We consider the new divisor 326 and the new remainder 172, and apply the division lemma to get

326 = 172 x 1 + 154

We consider the new divisor 172 and the new remainder 154,and apply the division lemma to get

172 = 154 x 1 + 18

We consider the new divisor 154 and the new remainder 18,and apply the division lemma to get

154 = 18 x 8 + 10

We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get

18 = 10 x 1 + 8

We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get

10 = 8 x 1 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 824 and 498 is 2

Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(154,18) = HCF(172,154) = HCF(326,172) = HCF(498,326) = HCF(824,498) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 20 > 2, we apply the division lemma to 20 and 2, to get

20 = 2 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 20 is 2

Notice that 2 = HCF(20,2) .
