HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 346, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 656, 346, 231 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 656, 346, 231 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 656, 346, 231 is 1.

HCF(656, 346, 231) = 1

Highest common factor (HCF) of 656, 346, 231 is 1.

Highest Common Factor of 656,346,231 using Euclid's algorithm

Highest Common Factor of 656,346,231 is 1

Step 1: Since 656 > 346, we apply the division lemma to 656 and 346, to get

656 = 346 x 1 + 310

Step 2: Since the reminder 346 ≠ 0, we apply division lemma to 310 and 346, to get

346 = 310 x 1 + 36

Step 3: We consider the new divisor 310 and the new remainder 36, and apply the division lemma to get

310 = 36 x 8 + 22

We consider the new divisor 36 and the new remainder 22,and apply the division lemma to get

36 = 22 x 1 + 14

We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get

22 = 14 x 1 + 8

We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get

14 = 8 x 1 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 656 and 346 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(36,22) = HCF(310,36) = HCF(346,310) = HCF(656,346) .

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

Step 1: Since 231 > 2, we apply the division lemma to 231 and 2, to get

231 = 2 x 115 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 231 is 1

Notice that 1 = HCF(2,1) = HCF(231,2) .
