HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 971, 807, 342 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 971, 807, 342 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 971, 807, 342 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 971, 807, 342 is 1.

HCF(971, 807, 342) = 1

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

HCF of:

Highest common factor (HCF) of 971, 807, 342 is 1.

Highest Common Factor of 971,807,342 using Euclid's algorithm

Highest Common Factor of 971,807,342 is 1

Step 1: Since 971 > 807, we apply the division lemma to 971 and 807, to get

971 = 807 x 1 + 164

Step 2: Since the reminder 807 ≠ 0, we apply division lemma to 164 and 807, to get

807 = 164 x 4 + 151

Step 3: We consider the new divisor 164 and the new remainder 151, and apply the division lemma to get

164 = 151 x 1 + 13

We consider the new divisor 151 and the new remainder 13,and apply the division lemma to get

151 = 13 x 11 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 971 and 807 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(151,13) = HCF(164,151) = HCF(807,164) = HCF(971,807) .


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

Step 1: Since 342 > 1, we apply the division lemma to 342 and 1, to get

342 = 1 x 342 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 342 is 1

Notice that 1 = HCF(342,1) .
