HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 917 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 831, 917 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 831, 917 is 1.
HCF(831, 917) = 1
HCF of 831, 917 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 917 is 1.
Highest Common Factor of 831,917 is 1
Step 1: Since 917 > 831, we apply the division lemma to 917 and 831, to get
917 = 831 x 1 + 86
Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 86 and 831, to get
831 = 86 x 9 + 57
Step 3: We consider the new divisor 86 and the new remainder 57, and apply the division lemma to get
86 = 57 x 1 + 29
We consider the new divisor 57 and the new remainder 29,and apply the division lemma to get
57 = 29 x 1 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 831 and 917 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(57,29) = HCF(86,57) = HCF(831,86) = HCF(917,831) .
