HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 801, 281, 470 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 801, 281, 470 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 801, 281, 470 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 801, 281, 470 is 1.

HCF(801, 281, 470) = 1

Highest common factor (HCF) of 801, 281, 470 is 1.

Highest Common Factor of 801,281,470 using Euclid's algorithm

Highest Common Factor of 801,281,470 is 1

Step 1: Since 801 > 281, we apply the division lemma to 801 and 281, to get

801 = 281 x 2 + 239

Step 2: Since the reminder 281 ≠ 0, we apply division lemma to 239 and 281, to get

281 = 239 x 1 + 42

Step 3: We consider the new divisor 239 and the new remainder 42, and apply the division lemma to get

239 = 42 x 5 + 29

We consider the new divisor 42 and the new remainder 29,and apply the division lemma to get

42 = 29 x 1 + 13

We consider the new divisor 29 and the new remainder 13,and apply the division lemma to get

29 = 13 x 2 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 801 and 281 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(29,13) = HCF(42,29) = HCF(239,42) = HCF(281,239) = HCF(801,281) .

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

Step 1: Since 470 > 1, we apply the division lemma to 470 and 1, to get

470 = 1 x 470 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 470 is 1

Notice that 1 = HCF(470,1) .
