HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 206, 178 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 206, 178 is 2 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 206, 178 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 206, 178 is 2.

HCF(206, 178) = 2

HCF of 206, 178 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 206, 178 is 2.

Highest Common Factor of 206,178 using Euclid's algorithm

Highest Common Factor of 206,178 is 2

Step 1: Since 206 > 178, we apply the division lemma to 206 and 178, to get

206 = 178 x 1 + 28

Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 28 and 178, to get

178 = 28 x 6 + 10

Step 3: We consider the new divisor 28 and the new remainder 10, and apply the division lemma to get

28 = 10 x 2 + 8

We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get

10 = 8 x 1 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 206 and 178 is 2

Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(178,28) = HCF(206,178) .
