HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 336, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 820, 336, 447 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 820, 336, 447 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 820, 336, 447 is 1.

HCF(820, 336, 447) = 1

Highest common factor (HCF) of 820, 336, 447 is 1.

Highest Common Factor of 820,336,447 using Euclid's algorithm

Highest Common Factor of 820,336,447 is 1

Step 1: Since 820 > 336, we apply the division lemma to 820 and 336, to get

820 = 336 x 2 + 148

Step 2: Since the reminder 336 ≠ 0, we apply division lemma to 148 and 336, to get

336 = 148 x 2 + 40

Step 3: We consider the new divisor 148 and the new remainder 40, and apply the division lemma to get

148 = 40 x 3 + 28

We consider the new divisor 40 and the new remainder 28,and apply the division lemma to get

40 = 28 x 1 + 12

We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get

28 = 12 x 2 + 4

We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get

12 = 4 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 820 and 336 is 4

Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(148,40) = HCF(336,148) = HCF(820,336) .


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

Step 1: Since 447 > 4, we apply the division lemma to 447 and 4, to get

447 = 4 x 111 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: 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 4 and 447 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(447,4) .
