HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 634, 447 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 634, 447 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 634, 447 is 1.

HCF(634, 447) = 1

Highest common factor (HCF) of 634, 447 is 1.

Highest Common Factor of 634,447 using Euclid's algorithm

Highest Common Factor of 634,447 is 1

Step 1: Since 634 > 447, we apply the division lemma to 634 and 447, to get

634 = 447 x 1 + 187

Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 187 and 447, to get

447 = 187 x 2 + 73

Step 3: We consider the new divisor 187 and the new remainder 73, and apply the division lemma to get

187 = 73 x 2 + 41

We consider the new divisor 73 and the new remainder 41,and apply the division lemma to get

73 = 41 x 1 + 32

We consider the new divisor 41 and the new remainder 32,and apply the division lemma to get

41 = 32 x 1 + 9

We consider the new divisor 32 and the new remainder 9,and apply the division lemma to get

32 = 9 x 3 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 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 634 and 447 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(32,9) = HCF(41,32) = HCF(73,41) = HCF(187,73) = HCF(447,187) = HCF(634,447) .
