HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 156, 860, 394 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 156, 860, 394 is 2 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 156, 860, 394 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 156, 860, 394 is 2.

HCF(156, 860, 394) = 2

HCF of 156, 860, 394 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 156, 860, 394 is 2.

Highest Common Factor of 156,860,394 using Euclid's algorithm

Highest Common Factor of 156,860,394 is 2

Step 1: Since 860 > 156, we apply the division lemma to 860 and 156, to get

860 = 156 x 5 + 80

Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 80 and 156, to get

156 = 80 x 1 + 76

Step 3: We consider the new divisor 80 and the new remainder 76, and apply the division lemma to get

80 = 76 x 1 + 4

We consider the new divisor 76 and the new remainder 4, and apply the division lemma to get

76 = 4 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 156 and 860 is 4

Notice that 4 = HCF(76,4) = HCF(80,76) = HCF(156,80) = HCF(860,156) .


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

Step 1: Since 394 > 4, we apply the division lemma to 394 and 4, to get

394 = 4 x 98 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 394 is 2

Notice that 2 = HCF(4,2) = HCF(394,4) .
