HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 9143 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 9143 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 870, 9143 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 870, 9143 is 1.
HCF(870, 9143) = 1
HCF of 870, 9143 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 9143 is 1.
Highest Common Factor of 870,9143 is 1
Step 1: Since 9143 > 870, we apply the division lemma to 9143 and 870, to get
9143 = 870 x 10 + 443
Step 2: Since the reminder 870 ≠ 0, we apply division lemma to 443 and 870, to get
870 = 443 x 1 + 427
Step 3: We consider the new divisor 443 and the new remainder 427, and apply the division lemma to get
443 = 427 x 1 + 16
We consider the new divisor 427 and the new remainder 16,and apply the division lemma to get
427 = 16 x 26 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 870 and 9143 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(427,16) = HCF(443,427) = HCF(870,443) = HCF(9143,870) .
