HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 866, 470 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 655, 866, 470 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 655, 866, 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 655, 866, 470 is 1.

HCF(655, 866, 470) = 1

HCF of 655, 866, 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 655, 866, 470 is 1.

Highest Common Factor of 655,866,470 using Euclid's algorithm

Highest Common Factor of 655,866,470 is 1

Step 1: Since 866 > 655, we apply the division lemma to 866 and 655, to get

866 = 655 x 1 + 211

Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 211 and 655, to get

655 = 211 x 3 + 22

Step 3: We consider the new divisor 211 and the new remainder 22, and apply the division lemma to get

211 = 22 x 9 + 13

We consider the new divisor 22 and the new remainder 13,and apply the division lemma to get

22 = 13 x 1 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 866 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(211,22) = HCF(655,211) = HCF(866,655) .

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

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

470 = 1 x 470 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 470 is 1

Notice that 1 = HCF(470,1) .
