HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 847, 2861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 847, 2861 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 847, 2861 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 847, 2861 is 1.
HCF(847, 2861) = 1
HCF of 847, 2861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 847, 2861 is 1.
Highest Common Factor of 847,2861 is 1
Step 1: Since 2861 > 847, we apply the division lemma to 2861 and 847, to get
2861 = 847 x 3 + 320
Step 2: Since the reminder 847 ≠ 0, we apply division lemma to 320 and 847, to get
847 = 320 x 2 + 207
Step 3: We consider the new divisor 320 and the new remainder 207, and apply the division lemma to get
320 = 207 x 1 + 113
We consider the new divisor 207 and the new remainder 113,and apply the division lemma to get
207 = 113 x 1 + 94
We consider the new divisor 113 and the new remainder 94,and apply the division lemma to get
113 = 94 x 1 + 19
We consider the new divisor 94 and the new remainder 19,and apply the division lemma to get
94 = 19 x 4 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 847 and 2861 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(94,19) = HCF(113,94) = HCF(207,113) = HCF(320,207) = HCF(847,320) = HCF(2861,847) .
