HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 474, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 617, 474, 471 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 617, 474, 471 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 617, 474, 471 is 1.

HCF(617, 474, 471) = 1

Highest common factor (HCF) of 617, 474, 471 is 1.

Highest Common Factor of 617,474,471 using Euclid's algorithm

Highest Common Factor of 617,474,471 is 1

Step 1: Since 617 > 474, we apply the division lemma to 617 and 474, to get

617 = 474 x 1 + 143

Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 143 and 474, to get

474 = 143 x 3 + 45

Step 3: We consider the new divisor 143 and the new remainder 45, and apply the division lemma to get

143 = 45 x 3 + 8

We consider the new divisor 45 and the new remainder 8,and apply the division lemma to get

45 = 8 x 5 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 617 and 474 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(45,8) = HCF(143,45) = HCF(474,143) = HCF(617,474) .

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

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

471 = 1 x 471 + 0

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

Notice that 1 = HCF(471,1) .
