HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 556, 940, 317 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 556, 940, 317 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 556, 940, 317 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 556, 940, 317 is 1.

HCF(556, 940, 317) = 1

Highest Common Factor of 556,940,317 using Euclid's algorithm

Highest Common Factor of 556,940,317 is 1

Step 1: Since 940 > 556, we apply the division lemma to 940 and 556, to get

940 = 556 x 1 + 384

Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 384 and 556, to get

556 = 384 x 1 + 172

Step 3: We consider the new divisor 384 and the new remainder 172, and apply the division lemma to get

384 = 172 x 2 + 40

We consider the new divisor 172 and the new remainder 40,and apply the division lemma to get

172 = 40 x 4 + 12

We consider the new divisor 40 and the new remainder 12,and apply the division lemma to get

40 = 12 x 3 + 4

We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get

12 = 4 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 556 and 940 is 4

Notice that 4 = HCF(12,4) = HCF(40,12) = HCF(172,40) = HCF(384,172) = HCF(556,384) = HCF(940,556) .

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

Step 1: Since 317 > 4, we apply the division lemma to 317 and 4, to get

317 = 4 x 79 + 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 317 is 1

Notice that 1 = HCF(4,1) = HCF(317,4) .
