HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 371, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 371, 523 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 371, 523 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 371, 523 is 1.

HCF(371, 523) = 1

Highest common factor (HCF) of 371, 523 is 1.

Highest Common Factor of 371,523 using Euclid's algorithm

Highest Common Factor of 371,523 is 1

Step 1: Since 523 > 371, we apply the division lemma to 523 and 371, to get

523 = 371 x 1 + 152

Step 2: Since the reminder 371 ≠ 0, we apply division lemma to 152 and 371, to get

371 = 152 x 2 + 67

Step 3: We consider the new divisor 152 and the new remainder 67, and apply the division lemma to get

152 = 67 x 2 + 18

We consider the new divisor 67 and the new remainder 18,and apply the division lemma to get

67 = 18 x 3 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 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 371 and 523 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(67,18) = HCF(152,67) = HCF(371,152) = HCF(523,371) .
