HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 585, 107 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 585, 107 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, 585, 107 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, 585, 107 is 1.

HCF(855, 585, 107) = 1

HCF of 855, 585, 107 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, 585, 107 is 1.

Highest Common Factor of 855,585,107 using Euclid's algorithm

Highest Common Factor of 855,585,107 is 1

Step 1: Since 855 > 585, we apply the division lemma to 855 and 585, to get

855 = 585 x 1 + 270

Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 270 and 585, to get

585 = 270 x 2 + 45

Step 3: We consider the new divisor 270 and the new remainder 45, and apply the division lemma to get

270 = 45 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 855 and 585 is 45

Notice that 45 = HCF(270,45) = HCF(585,270) = HCF(855,585) .


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

Step 1: Since 107 > 45, we apply the division lemma to 107 and 45, to get

107 = 45 x 2 + 17

Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 17 and 45, to get

45 = 17 x 2 + 11

Step 3: We consider the new divisor 17 and the new remainder 11, and apply the division lemma to get

17 = 11 x 1 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 45 and 107 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(45,17) = HCF(107,45) .
