HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 676, 258, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 676, 258, 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 676, 258, 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 676, 258, 231 is 1.

HCF(676, 258, 231) = 1

Highest Common Factor of 676,258,231 using Euclid's algorithm

Highest Common Factor of 676,258,231 is 1

Step 1: Since 676 > 258, we apply the division lemma to 676 and 258, to get

676 = 258 x 2 + 160

Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 160 and 258, to get

258 = 160 x 1 + 98

Step 3: We consider the new divisor 160 and the new remainder 98, and apply the division lemma to get

160 = 98 x 1 + 62

We consider the new divisor 98 and the new remainder 62,and apply the division lemma to get

98 = 62 x 1 + 36

We consider the new divisor 62 and the new remainder 36,and apply the division lemma to get

62 = 36 x 1 + 26

We consider the new divisor 36 and the new remainder 26,and apply the division lemma to get

36 = 26 x 1 + 10

We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get

26 = 10 x 2 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 676 and 258 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(36,26) = HCF(62,36) = HCF(98,62) = HCF(160,98) = HCF(258,160) = HCF(676,258) .

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) .
