HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 101, 158 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 101, 158 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 101, 158 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 101, 158 is 1.

HCF(101, 158) = 1

HCF of 101, 158 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 101, 158 is 1.

Highest Common Factor of 101,158 using Euclid's algorithm

Highest Common Factor of 101,158 is 1

Step 1: Since 158 > 101, we apply the division lemma to 158 and 101, to get

158 = 101 x 1 + 57

Step 2: Since the reminder 101 ≠ 0, we apply division lemma to 57 and 101, to get

101 = 57 x 1 + 44

Step 3: We consider the new divisor 57 and the new remainder 44, and apply the division lemma to get

57 = 44 x 1 + 13

We consider the new divisor 44 and the new remainder 13,and apply the division lemma to get

44 = 13 x 3 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 101 and 158 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(57,44) = HCF(101,57) = HCF(158,101) .
