HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 380, 691 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 708, 380, 691 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 708, 380, 691 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 708, 380, 691 is 1.

HCF(708, 380, 691) = 1

HCF of 708, 380, 691 using Euclid's algorithm

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

Highest common factor (HCF) of 708, 380, 691 is 1.

Highest Common Factor of 708,380,691 using Euclid's algorithm

Highest Common Factor of 708,380,691 is 1

Step 1: Since 708 > 380, we apply the division lemma to 708 and 380, to get

708 = 380 x 1 + 328

Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 328 and 380, to get

380 = 328 x 1 + 52

Step 3: We consider the new divisor 328 and the new remainder 52, and apply the division lemma to get

328 = 52 x 6 + 16

We consider the new divisor 52 and the new remainder 16,and apply the division lemma to get

52 = 16 x 3 + 4

We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 708 and 380 is 4

Notice that 4 = HCF(16,4) = HCF(52,16) = HCF(328,52) = HCF(380,328) = HCF(708,380) .

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

Step 1: Since 691 > 4, we apply the division lemma to 691 and 4, to get

691 = 4 x 172 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 691 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(691,4) .
