HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 707, 971, 115 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 707, 971, 115 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 707, 971, 115 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 707, 971, 115 is 1.

HCF(707, 971, 115) = 1

HCF of 707, 971, 115 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 707, 971, 115 is 1.

Highest Common Factor of 707,971,115 using Euclid's algorithm

Highest Common Factor of 707,971,115 is 1

Step 1: Since 971 > 707, we apply the division lemma to 971 and 707, to get

971 = 707 x 1 + 264

Step 2: Since the reminder 707 ≠ 0, we apply division lemma to 264 and 707, to get

707 = 264 x 2 + 179

Step 3: We consider the new divisor 264 and the new remainder 179, and apply the division lemma to get

264 = 179 x 1 + 85

We consider the new divisor 179 and the new remainder 85,and apply the division lemma to get

179 = 85 x 2 + 9

We consider the new divisor 85 and the new remainder 9,and apply the division lemma to get

85 = 9 x 9 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 707 and 971 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(85,9) = HCF(179,85) = HCF(264,179) = HCF(707,264) = HCF(971,707) .

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

Step 1: Since 115 > 1, we apply the division lemma to 115 and 1, to get

115 = 1 x 115 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 115 is 1

Notice that 1 = HCF(115,1) .
