HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 860, 546, 470 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 860, 546, 470 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 860, 546, 470 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 860, 546, 470 is 2.

HCF(860, 546, 470) = 2

HCF of 860, 546, 470 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 860, 546, 470 is 2.

Highest Common Factor of 860,546,470 using Euclid's algorithm

Highest Common Factor of 860,546,470 is 2

Step 1: Since 860 > 546, we apply the division lemma to 860 and 546, to get

860 = 546 x 1 + 314

Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 314 and 546, to get

546 = 314 x 1 + 232

Step 3: We consider the new divisor 314 and the new remainder 232, and apply the division lemma to get

314 = 232 x 1 + 82

We consider the new divisor 232 and the new remainder 82,and apply the division lemma to get

232 = 82 x 2 + 68

We consider the new divisor 82 and the new remainder 68,and apply the division lemma to get

82 = 68 x 1 + 14

We consider the new divisor 68 and the new remainder 14,and apply the division lemma to get

68 = 14 x 4 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 860 and 546 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(68,14) = HCF(82,68) = HCF(232,82) = HCF(314,232) = HCF(546,314) = HCF(860,546) .

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

Step 1: Since 470 > 2, we apply the division lemma to 470 and 2, to get

470 = 2 x 235 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 470 is 2

Notice that 2 = HCF(470,2) .
