HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 23, 427, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 23, 427, 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 23, 427, 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 23, 427, 523 is 1.

HCF(23, 427, 523) = 1

Highest common factor (HCF) of 23, 427, 523 is 1.

Highest Common Factor of 23,427,523 using Euclid's algorithm

Highest Common Factor of 23,427,523 is 1

Step 1: Since 427 > 23, we apply the division lemma to 427 and 23, to get

427 = 23 x 18 + 13

Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 13 and 23, to get

23 = 13 x 1 + 10

Step 3: We consider the new divisor 13 and the new remainder 10, and apply the division lemma to get

13 = 10 x 1 + 3

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

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 427 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(427,23) .


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

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

523 = 1 x 523 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 523 is 1

Notice that 1 = HCF(523,1) .
