HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 939, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 680, 939, 207 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 680, 939, 207 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, 939, 207 is 1.

HCF(680, 939, 207) = 1

HCF of 680, 939, 207 using Euclid's algorithm

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

Highest common factor (HCF) of 680, 939, 207 is 1.

Highest Common Factor of 680,939,207 using Euclid's algorithm

Highest Common Factor of 680,939,207 is 1

Step 1: Since 939 > 680, we apply the division lemma to 939 and 680, to get

939 = 680 x 1 + 259

Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 259 and 680, to get

680 = 259 x 2 + 162

Step 3: We consider the new divisor 259 and the new remainder 162, and apply the division lemma to get

259 = 162 x 1 + 97

We consider the new divisor 162 and the new remainder 97,and apply the division lemma to get

162 = 97 x 1 + 65

We consider the new divisor 97 and the new remainder 65,and apply the division lemma to get

97 = 65 x 1 + 32

We consider the new divisor 65 and the new remainder 32,and apply the division lemma to get

65 = 32 x 2 + 1

We consider the new divisor 32 and the new remainder 1,and apply the division lemma to get

32 = 1 x 32 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 680 and 939 is 1

Notice that 1 = HCF(32,1) = HCF(65,32) = HCF(97,65) = HCF(162,97) = HCF(259,162) = HCF(680,259) = HCF(939,680) .

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

Step 1: Since 207 > 1, we apply the division lemma to 207 and 1, to get

207 = 1 x 207 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 207 is 1

Notice that 1 = HCF(207,1) .
