HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 471, 842 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 635, 471, 842 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 635, 471, 842 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 635, 471, 842 is 1.

HCF(635, 471, 842) = 1

HCF of 635, 471, 842 using Euclid's algorithm

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

Highest common factor (HCF) of 635, 471, 842 is 1.

Highest Common Factor of 635,471,842 using Euclid's algorithm

Highest Common Factor of 635,471,842 is 1

Step 1: Since 635 > 471, we apply the division lemma to 635 and 471, to get

635 = 471 x 1 + 164

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 164 and 471, to get

471 = 164 x 2 + 143

Step 3: We consider the new divisor 164 and the new remainder 143, and apply the division lemma to get

164 = 143 x 1 + 21

We consider the new divisor 143 and the new remainder 21,and apply the division lemma to get

143 = 21 x 6 + 17

We consider the new divisor 21 and the new remainder 17,and apply the division lemma to get

21 = 17 x 1 + 4

We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get

17 = 4 x 4 + 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 635 and 471 is 1

Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(21,17) = HCF(143,21) = HCF(164,143) = HCF(471,164) = HCF(635,471) .

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

Step 1: Since 842 > 1, we apply the division lemma to 842 and 1, to get

842 = 1 x 842 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 842 is 1

Notice that 1 = HCF(842,1) .
