HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 970, 836 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 680, 970, 836 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 680, 970, 836 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 680, 970, 836 is 2.

HCF(680, 970, 836) = 2

HCF of 680, 970, 836 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 680, 970, 836 is 2.

Highest Common Factor of 680,970,836 using Euclid's algorithm

Highest Common Factor of 680,970,836 is 2

Step 1: Since 970 > 680, we apply the division lemma to 970 and 680, to get

970 = 680 x 1 + 290

Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 290 and 680, to get

680 = 290 x 2 + 100

Step 3: We consider the new divisor 290 and the new remainder 100, and apply the division lemma to get

290 = 100 x 2 + 90

We consider the new divisor 100 and the new remainder 90,and apply the division lemma to get

100 = 90 x 1 + 10

We consider the new divisor 90 and the new remainder 10,and apply the division lemma to get

90 = 10 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 680 and 970 is 10

Notice that 10 = HCF(90,10) = HCF(100,90) = HCF(290,100) = HCF(680,290) = HCF(970,680) .


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

Step 1: Since 836 > 10, we apply the division lemma to 836 and 10, to get

836 = 10 x 83 + 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 836 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(836,10) .
