HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 82498 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 82498 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, 82498 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, 82498 is 2.
HCF(838, 82498) = 2
HCF of 838, 82498 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, 82498 is 2.
Highest Common Factor of 838,82498 is 2
Step 1: Since 82498 > 838, we apply the division lemma to 82498 and 838, to get
82498 = 838 x 98 + 374
Step 2: Since the reminder 838 ≠ 0, we apply division lemma to 374 and 838, to get
838 = 374 x 2 + 90
Step 3: We consider the new divisor 374 and the new remainder 90, and apply the division lemma to get
374 = 90 x 4 + 14
We consider the new divisor 90 and the new remainder 14,and apply the division lemma to get
90 = 14 x 6 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 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 838 and 82498 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(90,14) = HCF(374,90) = HCF(838,374) = HCF(82498,838) .
