HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 516, 856, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 516, 856, 349 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 516, 856, 349 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 516, 856, 349 is 1.

HCF(516, 856, 349) = 1

Highest common factor (HCF) of 516, 856, 349 is 1.

Highest Common Factor of 516,856,349 using Euclid's algorithm

Highest Common Factor of 516,856,349 is 1

Step 1: Since 856 > 516, we apply the division lemma to 856 and 516, to get

856 = 516 x 1 + 340

Step 2: Since the reminder 516 ≠ 0, we apply division lemma to 340 and 516, to get

516 = 340 x 1 + 176

Step 3: We consider the new divisor 340 and the new remainder 176, and apply the division lemma to get

340 = 176 x 1 + 164

We consider the new divisor 176 and the new remainder 164,and apply the division lemma to get

176 = 164 x 1 + 12

We consider the new divisor 164 and the new remainder 12,and apply the division lemma to get

164 = 12 x 13 + 8

We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get

12 = 8 x 1 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 516 and 856 is 4

Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(164,12) = HCF(176,164) = HCF(340,176) = HCF(516,340) = HCF(856,516) .

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

Step 1: Since 349 > 4, we apply the division lemma to 349 and 4, to get

349 = 4 x 87 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 349 is 1

Notice that 1 = HCF(4,1) = HCF(349,4) .
