HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 205, 534 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 205, 534 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 855, 205, 534 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 855, 205, 534 is 1.

HCF(855, 205, 534) = 1

HCF of 855, 205, 534 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 855, 205, 534 is 1.

Highest Common Factor of 855,205,534 using Euclid's algorithm

Highest Common Factor of 855,205,534 is 1

Step 1: Since 855 > 205, we apply the division lemma to 855 and 205, to get

855 = 205 x 4 + 35

Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 35 and 205, to get

205 = 35 x 5 + 30

Step 3: We consider the new divisor 35 and the new remainder 30, and apply the division lemma to get

35 = 30 x 1 + 5

We consider the new divisor 30 and the new remainder 5, and apply the division lemma to get

30 = 5 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 855 and 205 is 5

Notice that 5 = HCF(30,5) = HCF(35,30) = HCF(205,35) = HCF(855,205) .

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

Step 1: Since 534 > 5, we apply the division lemma to 534 and 5, to get

534 = 5 x 106 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: 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 5 and 534 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(534,5) .
