HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 312 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 312 is 3 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, 312 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, 312 is 3.
HCF(831, 312) = 3
HCF of 831, 312 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, 312 is 3.
Highest Common Factor of 831,312 is 3
Step 1: Since 831 > 312, we apply the division lemma to 831 and 312, to get
831 = 312 x 2 + 207
Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 207 and 312, to get
312 = 207 x 1 + 105
Step 3: We consider the new divisor 207 and the new remainder 105, and apply the division lemma to get
207 = 105 x 1 + 102
We consider the new divisor 105 and the new remainder 102,and apply the division lemma to get
105 = 102 x 1 + 3
We consider the new divisor 102 and the new remainder 3,and apply the division lemma to get
102 = 3 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 312 is 3
Notice that 3 = HCF(102,3) = HCF(105,102) = HCF(207,105) = HCF(312,207) = HCF(831,312) .
