HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 796, 886 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 470, 796, 886 is 2 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 470, 796, 886 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 470, 796, 886 is 2.
HCF(470, 796, 886) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 470, 796, 886 is 2.
Step 1: Since 796 > 470, we apply the division lemma to 796 and 470, to get
796 = 470 x 1 + 326
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 326 and 470, to get
470 = 326 x 1 + 144
Step 3: We consider the new divisor 326 and the new remainder 144, and apply the division lemma to get
326 = 144 x 2 + 38
We consider the new divisor 144 and the new remainder 38,and apply the division lemma to get
144 = 38 x 3 + 30
We consider the new divisor 38 and the new remainder 30,and apply the division lemma to get
38 = 30 x 1 + 8
We consider the new divisor 30 and the new remainder 8,and apply the division lemma to get
30 = 8 x 3 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 470 and 796 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(30,8) = HCF(38,30) = HCF(144,38) = HCF(326,144) = HCF(470,326) = HCF(796,470) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 886 > 2, we apply the division lemma to 886 and 2, to get
886 = 2 x 443 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 886 is 2
Notice that 2 = HCF(886,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
