HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 486 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 486 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 838, 486 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 838, 486 is 2.
HCF(838, 486) = 2
HCF of 838, 486 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 486 is 2.
Highest Common Factor of 838,486 is 2
Step 1: Since 838 > 486, we apply the division lemma to 838 and 486, to get
838 = 486 x 1 + 352
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 352 and 486, to get
486 = 352 x 1 + 134
Step 3: We consider the new divisor 352 and the new remainder 134, and apply the division lemma to get
352 = 134 x 2 + 84
We consider the new divisor 134 and the new remainder 84,and apply the division lemma to get
134 = 84 x 1 + 50
We consider the new divisor 84 and the new remainder 50,and apply the division lemma to get
84 = 50 x 1 + 34
We consider the new divisor 50 and the new remainder 34,and apply the division lemma to get
50 = 34 x 1 + 16
We consider the new divisor 34 and the new remainder 16,and apply the division lemma to get
34 = 16 x 2 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 486 is 2
Notice that 2 = HCF(16,2) = HCF(34,16) = HCF(50,34) = HCF(84,50) = HCF(134,84) = HCF(352,134) = HCF(486,352) = HCF(838,486) .
