HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 353, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 990, 353, 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 990, 353, 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 990, 353, 326 is 1.

HCF(990, 353, 326) = 1

Highest common factor (HCF) of 990, 353, 326 is 1.

Highest Common Factor of 990,353,326 using Euclid's algorithm

Highest Common Factor of 990,353,326 is 1

Step 1: Since 990 > 353, we apply the division lemma to 990 and 353, to get

990 = 353 x 2 + 284

Step 2: Since the reminder 353 ≠ 0, we apply division lemma to 284 and 353, to get

353 = 284 x 1 + 69

Step 3: We consider the new divisor 284 and the new remainder 69, and apply the division lemma to get

284 = 69 x 4 + 8

We consider the new divisor 69 and the new remainder 8,and apply the division lemma to get

69 = 8 x 8 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

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

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 990 and 353 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(69,8) = HCF(284,69) = HCF(353,284) = HCF(990,353) .

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) .
