HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 998, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 831, 998, 957 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 831, 998, 957 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 831, 998, 957 is 1.

HCF(831, 998, 957) = 1

HCF of 831, 998, 957 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 831, 998, 957 is 1.

Highest Common Factor of 831,998,957 using Euclid's algorithm

Highest Common Factor of 831,998,957 is 1

Step 1: Since 998 > 831, we apply the division lemma to 998 and 831, to get

998 = 831 x 1 + 167

Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 167 and 831, to get

831 = 167 x 4 + 163

Step 3: We consider the new divisor 167 and the new remainder 163, and apply the division lemma to get

167 = 163 x 1 + 4

We consider the new divisor 163 and the new remainder 4,and apply the division lemma to get

163 = 4 x 40 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 831 and 998 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(163,4) = HCF(167,163) = HCF(831,167) = HCF(998,831) .

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

Step 1: Since 957 > 1, we apply the division lemma to 957 and 1, to get

957 = 1 x 957 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 957 is 1

Notice that 1 = HCF(957,1) .
