HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 857, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 338, 857, 163 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 338, 857, 163 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 338, 857, 163 is 1.

HCF(338, 857, 163) = 1

HCF of 338, 857, 163 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 338, 857, 163 is 1.

Highest Common Factor of 338,857,163 using Euclid's algorithm

Highest Common Factor of 338,857,163 is 1

Step 1: Since 857 > 338, we apply the division lemma to 857 and 338, to get

857 = 338 x 2 + 181

Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 181 and 338, to get

338 = 181 x 1 + 157

Step 3: We consider the new divisor 181 and the new remainder 157, and apply the division lemma to get

181 = 157 x 1 + 24

We consider the new divisor 157 and the new remainder 24,and apply the division lemma to get

157 = 24 x 6 + 13

We consider the new divisor 24 and the new remainder 13,and apply the division lemma to get

24 = 13 x 1 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 338 and 857 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(24,13) = HCF(157,24) = HCF(181,157) = HCF(338,181) = HCF(857,338) .

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

Step 1: Since 163 > 1, we apply the division lemma to 163 and 1, to get

163 = 1 x 163 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 163 is 1

Notice that 1 = HCF(163,1) .
