HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 159 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 268, 159 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 268, 159 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 268, 159 is 1.

HCF(268, 159) = 1

HCF of 268, 159 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 268, 159 is 1.

Highest Common Factor of 268,159 using Euclid's algorithm

Highest Common Factor of 268,159 is 1

Step 1: Since 268 > 159, we apply the division lemma to 268 and 159, to get

268 = 159 x 1 + 109

Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 109 and 159, to get

159 = 109 x 1 + 50

Step 3: We consider the new divisor 109 and the new remainder 50, and apply the division lemma to get

109 = 50 x 2 + 9

We consider the new divisor 50 and the new remainder 9,and apply the division lemma to get

50 = 9 x 5 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 268 and 159 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(50,9) = HCF(109,50) = HCF(159,109) = HCF(268,159) .
