HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 905, 523, 472 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 905, 523, 472 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 905, 523, 472 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 905, 523, 472 is 1.

HCF(905, 523, 472) = 1

Highest common factor (HCF) of 905, 523, 472 is 1.

Highest Common Factor of 905,523,472 using Euclid's algorithm

Highest Common Factor of 905,523,472 is 1

Step 1: Since 905 > 523, we apply the division lemma to 905 and 523, to get

905 = 523 x 1 + 382

Step 2: Since the reminder 523 ≠ 0, we apply division lemma to 382 and 523, to get

523 = 382 x 1 + 141

Step 3: We consider the new divisor 382 and the new remainder 141, and apply the division lemma to get

382 = 141 x 2 + 100

We consider the new divisor 141 and the new remainder 100,and apply the division lemma to get

141 = 100 x 1 + 41

We consider the new divisor 100 and the new remainder 41,and apply the division lemma to get

100 = 41 x 2 + 18

We consider the new divisor 41 and the new remainder 18,and apply the division lemma to get

41 = 18 x 2 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 905 and 523 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(41,18) = HCF(100,41) = HCF(141,100) = HCF(382,141) = HCF(523,382) = HCF(905,523) .

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

Step 1: Since 472 > 1, we apply the division lemma to 472 and 1, to get

472 = 1 x 472 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 472 is 1

Notice that 1 = HCF(472,1) .
