HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 385, 631 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 385, 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 385, 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 385, 631 is 1.

HCF(385, 631) = 1

Highest Common Factor of 385,631 using Euclid's algorithm

Highest Common Factor of 385,631 is 1

Step 1: Since 631 > 385, we apply the division lemma to 631 and 385, to get

631 = 385 x 1 + 246

Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 246 and 385, to get

385 = 246 x 1 + 139

Step 3: We consider the new divisor 246 and the new remainder 139, and apply the division lemma to get

246 = 139 x 1 + 107

We consider the new divisor 139 and the new remainder 107,and apply the division lemma to get

139 = 107 x 1 + 32

We consider the new divisor 107 and the new remainder 32,and apply the division lemma to get

107 = 32 x 3 + 11

We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get

32 = 11 x 2 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 385 and 631 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(107,32) = HCF(139,107) = HCF(246,139) = HCF(385,246) = HCF(631,385) .
