HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1087, 8689 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1087, 8689 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 1087, 8689 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 1087, 8689 is 1.
HCF(1087, 8689) = 1
HCF of 1087, 8689 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1087, 8689 is 1.
Highest Common Factor of 1087,8689 is 1
Step 1: Since 8689 > 1087, we apply the division lemma to 8689 and 1087, to get
8689 = 1087 x 7 + 1080
Step 2: Since the reminder 1087 ≠ 0, we apply division lemma to 1080 and 1087, to get
1087 = 1080 x 1 + 7
Step 3: We consider the new divisor 1080 and the new remainder 7, and apply the division lemma to get
1080 = 7 x 154 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 1087 and 8689 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(1080,7) = HCF(1087,1080) = HCF(8689,1087) .
