HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6469, 8638 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6469, 8638 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 6469, 8638 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 6469, 8638 is 1.
HCF(6469, 8638) = 1
HCF of 6469, 8638 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6469, 8638 is 1.
Highest Common Factor of 6469,8638 is 1
Step 1: Since 8638 > 6469, we apply the division lemma to 8638 and 6469, to get
8638 = 6469 x 1 + 2169
Step 2: Since the reminder 6469 ≠ 0, we apply division lemma to 2169 and 6469, to get
6469 = 2169 x 2 + 2131
Step 3: We consider the new divisor 2169 and the new remainder 2131, and apply the division lemma to get
2169 = 2131 x 1 + 38
We consider the new divisor 2131 and the new remainder 38,and apply the division lemma to get
2131 = 38 x 56 + 3
We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get
38 = 3 x 12 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 6469 and 8638 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(2131,38) = HCF(2169,2131) = HCF(6469,2169) = HCF(8638,6469) .
