HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 326, 870, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 326, 870, 855 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 326, 870, 855 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 326, 870, 855 is 1.

HCF(326, 870, 855) = 1

HCF of 326, 870, 855 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 326, 870, 855 is 1.

Highest Common Factor of 326,870,855 using Euclid's algorithm

Highest Common Factor of 326,870,855 is 1

Step 1: Since 870 > 326, we apply the division lemma to 870 and 326, to get

870 = 326 x 2 + 218

Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 218 and 326, to get

326 = 218 x 1 + 108

Step 3: We consider the new divisor 218 and the new remainder 108, and apply the division lemma to get

218 = 108 x 2 + 2

We consider the new divisor 108 and the new remainder 2, and apply the division lemma to get

108 = 2 x 54 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 326 and 870 is 2

Notice that 2 = HCF(108,2) = HCF(218,108) = HCF(326,218) = HCF(870,326) .


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

Step 1: Since 855 > 2, we apply the division lemma to 855 and 2, to get

855 = 2 x 427 + 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 855 is 1

Notice that 1 = HCF(2,1) = HCF(855,2) .
