HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 695, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 261, 695, 12 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 261, 695, 12 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 261, 695, 12 is 1.

HCF(261, 695, 12) = 1

Highest common factor (HCF) of 261, 695, 12 is 1.

Highest Common Factor of 261,695,12 using Euclid's algorithm

Highest Common Factor of 261,695,12 is 1

Step 1: Since 695 > 261, we apply the division lemma to 695 and 261, to get

695 = 261 x 2 + 173

Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 173 and 261, to get

261 = 173 x 1 + 88

Step 3: We consider the new divisor 173 and the new remainder 88, and apply the division lemma to get

173 = 88 x 1 + 85

We consider the new divisor 88 and the new remainder 85,and apply the division lemma to get

88 = 85 x 1 + 3

We consider the new divisor 85 and the new remainder 3,and apply the division lemma to get

85 = 3 x 28 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 261 and 695 is 1

Notice that 1 = HCF(3,1) = HCF(85,3) = HCF(88,85) = HCF(173,88) = HCF(261,173) = HCF(695,261) .

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

Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1

Notice that 1 = HCF(12,1) .
