HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 84, 79, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 12, 84, 79, 326 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 12, 84, 79, 326 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 12, 84, 79, 326 is 1.

HCF(12, 84, 79, 326) = 1

## HCF of 12, 84, 79, 326 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 12, 84, 79, 326 is 1. ### Highest Common Factor of 12,84,79,326 is 1

Step 1: Since 84 > 12, we apply the division lemma to 84 and 12, to get

84 = 12 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 84 is 12

Notice that 12 = HCF(84,12) .

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

Step 1: Since 79 > 12, we apply the division lemma to 79 and 12, to get

79 = 12 x 6 + 7

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 7 and 12, to get

12 = 7 x 1 + 5

Step 3: We consider the new divisor 7 and the new remainder 5, and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 79 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(79,12) .

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

Step 1: Since 326 > 1, we apply the division lemma to 326 and 1, to get

326 = 1 x 326 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 326 is 1

Notice that 1 = HCF(326,1) .
