HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 158, 261, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 158, 261, 165 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 158, 261, 165 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 158, 261, 165 is 1.

HCF(158, 261, 165) = 1

HCF of 158, 261, 165 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 158, 261, 165 is 1.

Highest Common Factor of 158,261,165 using Euclid's algorithm

Highest Common Factor of 158,261,165 is 1

Step 1: Since 261 > 158, we apply the division lemma to 261 and 158, to get

261 = 158 x 1 + 103

Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 103 and 158, to get

158 = 103 x 1 + 55

Step 3: We consider the new divisor 103 and the new remainder 55, and apply the division lemma to get

103 = 55 x 1 + 48

We consider the new divisor 55 and the new remainder 48,and apply the division lemma to get

55 = 48 x 1 + 7

We consider the new divisor 48 and the new remainder 7,and apply the division lemma to get

48 = 7 x 6 + 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 158 and 261 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(48,7) = HCF(55,48) = HCF(103,55) = HCF(158,103) = HCF(261,158) .

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

Step 1: Since 165 > 1, we apply the division lemma to 165 and 1, to get

165 = 1 x 165 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 165 is 1

Notice that 1 = HCF(165,1) .
