HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 630 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 630 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, 630 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, 630 is 3.
HCF(831, 630) = 3
HCF of 831, 630 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, 630 is 3.
Highest Common Factor of 831,630 is 3
Step 1: Since 831 > 630, we apply the division lemma to 831 and 630, to get
831 = 630 x 1 + 201
Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 201 and 630, to get
630 = 201 x 3 + 27
Step 3: We consider the new divisor 201 and the new remainder 27, and apply the division lemma to get
201 = 27 x 7 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 630 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(201,27) = HCF(630,201) = HCF(831,630) .
