HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 85, 52, 705, 843 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 85, 52, 705, 843 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 85, 52, 705, 843 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 85, 52, 705, 843 is 1.

HCF(85, 52, 705, 843) = 1

Highest common factor (HCF) of 85, 52, 705, 843 is 1.

Highest Common Factor of 85,52,705,843 using Euclid's algorithm

Highest Common Factor of 85,52,705,843 is 1

Step 1: Since 85 > 52, we apply the division lemma to 85 and 52, to get

85 = 52 x 1 + 33

Step 2: Since the reminder 52 ≠ 0, we apply division lemma to 33 and 52, to get

52 = 33 x 1 + 19

Step 3: We consider the new divisor 33 and the new remainder 19, and apply the division lemma to get

33 = 19 x 1 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 85 and 52 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(33,19) = HCF(52,33) = HCF(85,52) .

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

Step 1: Since 705 > 1, we apply the division lemma to 705 and 1, to get

705 = 1 x 705 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 705 is 1

Notice that 1 = HCF(705,1) .

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

Step 1: Since 843 > 1, we apply the division lemma to 843 and 1, to get

843 = 1 x 843 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 843 is 1

Notice that 1 = HCF(843,1) .
