HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 490, 826 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 180, 490, 826 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 180, 490, 826 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 180, 490, 826 is 2.

HCF(180, 490, 826) = 2

Highest Common Factor of 180,490,826 using Euclid's algorithm

Highest Common Factor of 180,490,826 is 2

Step 1: Since 490 > 180, we apply the division lemma to 490 and 180, to get

490 = 180 x 2 + 130

Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 130 and 180, to get

180 = 130 x 1 + 50

Step 3: We consider the new divisor 130 and the new remainder 50, and apply the division lemma to get

130 = 50 x 2 + 30

We consider the new divisor 50 and the new remainder 30,and apply the division lemma to get

50 = 30 x 1 + 20

We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get

30 = 20 x 1 + 10

We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get

20 = 10 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 180 and 490 is 10

Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(50,30) = HCF(130,50) = HCF(180,130) = HCF(490,180) .

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

Step 1: Since 826 > 10, we apply the division lemma to 826 and 10, to get

826 = 10 x 82 + 6

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 6 and 10, to get

10 = 6 x 1 + 4

Step 3: We consider the new divisor 6 and the new remainder 4, and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 826 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(826,10) .
