HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 351, 529, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 351, 529, 686 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 351, 529, 686 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 351, 529, 686 is 1.

HCF(351, 529, 686) = 1

HCF of 351, 529, 686 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 351, 529, 686 is 1.

Highest Common Factor of 351,529,686 using Euclid's algorithm

Highest Common Factor of 351,529,686 is 1

Step 1: Since 529 > 351, we apply the division lemma to 529 and 351, to get

529 = 351 x 1 + 178

Step 2: Since the reminder 351 ≠ 0, we apply division lemma to 178 and 351, to get

351 = 178 x 1 + 173

Step 3: We consider the new divisor 178 and the new remainder 173, and apply the division lemma to get

178 = 173 x 1 + 5

We consider the new divisor 173 and the new remainder 5,and apply the division lemma to get

173 = 5 x 34 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 351 and 529 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(173,5) = HCF(178,173) = HCF(351,178) = HCF(529,351) .

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

Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get

686 = 1 x 686 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1

Notice that 1 = HCF(686,1) .
