HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 470 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 470 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 813, 470 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 813, 470 is 1.
HCF(813, 470) = 1
HCF of 813, 470 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 470 is 1.
Highest Common Factor of 813,470 is 1
Step 1: Since 813 > 470, we apply the division lemma to 813 and 470, to get
813 = 470 x 1 + 343
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 343 and 470, to get
470 = 343 x 1 + 127
Step 3: We consider the new divisor 343 and the new remainder 127, and apply the division lemma to get
343 = 127 x 2 + 89
We consider the new divisor 127 and the new remainder 89,and apply the division lemma to get
127 = 89 x 1 + 38
We consider the new divisor 89 and the new remainder 38,and apply the division lemma to get
89 = 38 x 2 + 13
We consider the new divisor 38 and the new remainder 13,and apply the division lemma to get
38 = 13 x 2 + 12
We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get
13 = 12 x 1 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 470 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(38,13) = HCF(89,38) = HCF(127,89) = HCF(343,127) = HCF(470,343) = HCF(813,470) .
