HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 631 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, 631 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, 631 is 1.

HCF(855, 631) = 1

Highest common factor (HCF) of 855, 631 is 1.

Highest Common Factor of 855,631 using Euclid's algorithm

Highest Common Factor of 855,631 is 1

Step 1: Since 855 > 631, we apply the division lemma to 855 and 631, to get

855 = 631 x 1 + 224

Step 2: Since the reminder 631 ≠ 0, we apply division lemma to 224 and 631, to get

631 = 224 x 2 + 183

Step 3: We consider the new divisor 224 and the new remainder 183, and apply the division lemma to get

224 = 183 x 1 + 41

We consider the new divisor 183 and the new remainder 41,and apply the division lemma to get

183 = 41 x 4 + 19

We consider the new divisor 41 and the new remainder 19,and apply the division lemma to get

41 = 19 x 2 + 3

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

19 = 3 x 6 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 855 and 631 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(41,19) = HCF(183,41) = HCF(224,183) = HCF(631,224) = HCF(855,631) .
