HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8581, 7647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8581, 7647 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 8581, 7647 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 8581, 7647 is 1.
HCF(8581, 7647) = 1
HCF of 8581, 7647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8581, 7647 is 1.
Highest Common Factor of 8581,7647 is 1
Step 1: Since 8581 > 7647, we apply the division lemma to 8581 and 7647, to get
8581 = 7647 x 1 + 934
Step 2: Since the reminder 7647 ≠ 0, we apply division lemma to 934 and 7647, to get
7647 = 934 x 8 + 175
Step 3: We consider the new divisor 934 and the new remainder 175, and apply the division lemma to get
934 = 175 x 5 + 59
We consider the new divisor 175 and the new remainder 59,and apply the division lemma to get
175 = 59 x 2 + 57
We consider the new divisor 59 and the new remainder 57,and apply the division lemma to get
59 = 57 x 1 + 2
We consider the new divisor 57 and the new remainder 2,and apply the division lemma to get
57 = 2 x 28 + 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 8581 and 7647 is 1
Notice that 1 = HCF(2,1) = HCF(57,2) = HCF(59,57) = HCF(175,59) = HCF(934,175) = HCF(7647,934) = HCF(8581,7647) .
