HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 704, 386, 261 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 704, 386, 261 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 704, 386, 261 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 704, 386, 261 is 1.

HCF(704, 386, 261) = 1

Highest common factor (HCF) of 704, 386, 261 is 1.

Highest Common Factor of 704,386,261 using Euclid's algorithm

Highest Common Factor of 704,386,261 is 1

Step 1: Since 704 > 386, we apply the division lemma to 704 and 386, to get

704 = 386 x 1 + 318

Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 318 and 386, to get

386 = 318 x 1 + 68

Step 3: We consider the new divisor 318 and the new remainder 68, and apply the division lemma to get

318 = 68 x 4 + 46

We consider the new divisor 68 and the new remainder 46,and apply the division lemma to get

68 = 46 x 1 + 22

We consider the new divisor 46 and the new remainder 22,and apply the division lemma to get

46 = 22 x 2 + 2

We consider the new divisor 22 and the new remainder 2,and apply the division lemma to get

22 = 2 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 704 and 386 is 2

Notice that 2 = HCF(22,2) = HCF(46,22) = HCF(68,46) = HCF(318,68) = HCF(386,318) = HCF(704,386) .

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

Step 1: Since 261 > 2, we apply the division lemma to 261 and 2, to get

261 = 2 x 130 + 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 261 is 1

Notice that 1 = HCF(2,1) = HCF(261,2) .
