HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 822, 712, 385 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 822, 712, 385 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 822, 712, 385 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 822, 712, 385 is 1.

HCF(822, 712, 385) = 1

Highest common factor (HCF) of 822, 712, 385 is 1.

Highest Common Factor of 822,712,385 using Euclid's algorithm

Highest Common Factor of 822,712,385 is 1

Step 1: Since 822 > 712, we apply the division lemma to 822 and 712, to get

822 = 712 x 1 + 110

Step 2: Since the reminder 712 ≠ 0, we apply division lemma to 110 and 712, to get

712 = 110 x 6 + 52

Step 3: We consider the new divisor 110 and the new remainder 52, and apply the division lemma to get

110 = 52 x 2 + 6

We consider the new divisor 52 and the new remainder 6,and apply the division lemma to get

52 = 6 x 8 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 822 and 712 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(52,6) = HCF(110,52) = HCF(712,110) = HCF(822,712) .

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

Step 1: Since 385 > 2, we apply the division lemma to 385 and 2, to get

385 = 2 x 192 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 385 is 1

Notice that 1 = HCF(2,1) = HCF(385,2) .
