HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 452, 472 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 819, 452, 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 819, 452, 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 819, 452, 472 is 1.

HCF(819, 452, 472) = 1

Highest common factor (HCF) of 819, 452, 472 is 1.

Highest Common Factor of 819,452,472 using Euclid's algorithm

Highest Common Factor of 819,452,472 is 1

Step 1: Since 819 > 452, we apply the division lemma to 819 and 452, to get

819 = 452 x 1 + 367

Step 2: Since the reminder 452 ≠ 0, we apply division lemma to 367 and 452, to get

452 = 367 x 1 + 85

Step 3: We consider the new divisor 367 and the new remainder 85, and apply the division lemma to get

367 = 85 x 4 + 27

We consider the new divisor 85 and the new remainder 27,and apply the division lemma to get

85 = 27 x 3 + 4

We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get

27 = 4 x 6 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 819 and 452 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(85,27) = HCF(367,85) = HCF(452,367) = HCF(819,452) .

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) .
