HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 263, 634 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 263, 634 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 263, 634 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 263, 634 is 1.

HCF(263, 634) = 1

HCF of 263, 634 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 263, 634 is 1.

Highest Common Factor of 263,634 using Euclid's algorithm

Highest Common Factor of 263,634 is 1

Step 1: Since 634 > 263, we apply the division lemma to 634 and 263, to get

634 = 263 x 2 + 108

Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 108 and 263, to get

263 = 108 x 2 + 47

Step 3: We consider the new divisor 108 and the new remainder 47, and apply the division lemma to get

108 = 47 x 2 + 14

We consider the new divisor 47 and the new remainder 14,and apply the division lemma to get

47 = 14 x 3 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

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 263 and 634 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(47,14) = HCF(108,47) = HCF(263,108) = HCF(634,263) .
