HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 871, 402, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 871, 402, 128 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 871, 402, 128 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 871, 402, 128 is 1.

HCF(871, 402, 128) = 1

HCF of 871, 402, 128 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 871, 402, 128 is 1.

Highest Common Factor of 871,402,128 using Euclid's algorithm

Highest Common Factor of 871,402,128 is 1

Step 1: Since 871 > 402, we apply the division lemma to 871 and 402, to get

871 = 402 x 2 + 67

Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 67 and 402, to get

402 = 67 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 67, the HCF of 871 and 402 is 67

Notice that 67 = HCF(402,67) = HCF(871,402) .


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

Step 1: Since 128 > 67, we apply the division lemma to 128 and 67, to get

128 = 67 x 1 + 61

Step 2: Since the reminder 67 ≠ 0, we apply division lemma to 61 and 67, to get

67 = 61 x 1 + 6

Step 3: We consider the new divisor 61 and the new remainder 6, and apply the division lemma to get

61 = 6 x 10 + 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 67 and 128 is 1

Notice that 1 = HCF(6,1) = HCF(61,6) = HCF(67,61) = HCF(128,67) .
