HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 65, 163 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 65, 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 65, 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 65, 163 is 1.

HCF(65, 163) = 1

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

HCF of:

Highest common factor (HCF) of 65, 163 is 1.

Highest Common Factor of 65,163 using Euclid's algorithm

Highest Common Factor of 65,163 is 1

Step 1: Since 163 > 65, we apply the division lemma to 163 and 65, to get

163 = 65 x 2 + 33

Step 2: Since the reminder 65 ≠ 0, we apply division lemma to 33 and 65, to get

65 = 33 x 1 + 32

Step 3: We consider the new divisor 33 and the new remainder 32, and apply the division lemma to get

33 = 32 x 1 + 1

We consider the new divisor 32 and the new remainder 1, and apply the division lemma to get

32 = 1 x 32 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 65 and 163 is 1

Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(65,33) = HCF(163,65) .
