HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 163, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 163, 197 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 163, 197 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 163, 197 is 1.

HCF(163, 197) = 1

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

HCF of:

Highest common factor (HCF) of 163, 197 is 1.

Highest Common Factor of 163,197 using Euclid's algorithm

Highest Common Factor of 163,197 is 1

Step 1: Since 197 > 163, we apply the division lemma to 197 and 163, to get

197 = 163 x 1 + 34

Step 2: Since the reminder 163 ≠ 0, we apply division lemma to 34 and 163, to get

163 = 34 x 4 + 27

Step 3: We consider the new divisor 34 and the new remainder 27, and apply the division lemma to get

34 = 27 x 1 + 7

We consider the new divisor 27 and the new remainder 7,and apply the division lemma to get

27 = 7 x 3 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 163 and 197 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(27,7) = HCF(34,27) = HCF(163,34) = HCF(197,163) .
