HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 317, 706, 26 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 487, 317, 706, 26 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 487, 317, 706, 26 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 487, 317, 706, 26 is 1.

HCF(487, 317, 706, 26) = 1

Highest common factor (HCF) of 487, 317, 706, 26 is 1.

Highest Common Factor of 487,317,706,26 using Euclid's algorithm

Highest Common Factor of 487,317,706,26 is 1

Step 1: Since 487 > 317, we apply the division lemma to 487 and 317, to get

487 = 317 x 1 + 170

Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 170 and 317, to get

317 = 170 x 1 + 147

Step 3: We consider the new divisor 170 and the new remainder 147, and apply the division lemma to get

170 = 147 x 1 + 23

We consider the new divisor 147 and the new remainder 23,and apply the division lemma to get

147 = 23 x 6 + 9

We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get

23 = 9 x 2 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 317 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(147,23) = HCF(170,147) = HCF(317,170) = HCF(487,317) .

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

Step 1: Since 706 > 1, we apply the division lemma to 706 and 1, to get

706 = 1 x 706 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 706 is 1

Notice that 1 = HCF(706,1) .

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

Step 1: Since 26 > 1, we apply the division lemma to 26 and 1, to get

26 = 1 x 26 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 26 is 1

Notice that 1 = HCF(26,1) .
