HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 814, 394 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 814, 394 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 471, 814, 394 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 471, 814, 394 is 1.

HCF(471, 814, 394) = 1

Highest common factor (HCF) of 471, 814, 394 is 1.

Highest Common Factor of 471,814,394 using Euclid's algorithm

Highest Common Factor of 471,814,394 is 1

Step 1: Since 814 > 471, we apply the division lemma to 814 and 471, to get

814 = 471 x 1 + 343

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 343 and 471, to get

471 = 343 x 1 + 128

Step 3: We consider the new divisor 343 and the new remainder 128, and apply the division lemma to get

343 = 128 x 2 + 87

We consider the new divisor 128 and the new remainder 87,and apply the division lemma to get

128 = 87 x 1 + 41

We consider the new divisor 87 and the new remainder 41,and apply the division lemma to get

87 = 41 x 2 + 5

We consider the new divisor 41 and the new remainder 5,and apply the division lemma to get

41 = 5 x 8 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 471 and 814 is 1

Notice that 1 = HCF(5,1) = HCF(41,5) = HCF(87,41) = HCF(128,87) = HCF(343,128) = HCF(471,343) = HCF(814,471) .

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

Step 1: Since 394 > 1, we apply the division lemma to 394 and 1, to get

394 = 1 x 394 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 394 is 1

Notice that 1 = HCF(394,1) .
