HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 462 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 462 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, 462 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, 462 is 2.
HCF(838, 462) = 2
HCF of 838, 462 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, 462 is 2.
Highest Common Factor of 838,462 is 2
Step 1: Since 838 > 462, we apply the division lemma to 838 and 462, to get
838 = 462 x 1 + 376
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 376 and 462, to get
462 = 376 x 1 + 86
Step 3: We consider the new divisor 376 and the new remainder 86, and apply the division lemma to get
376 = 86 x 4 + 32
We consider the new divisor 86 and the new remainder 32,and apply the division lemma to get
86 = 32 x 2 + 22
We consider the new divisor 32 and the new remainder 22,and apply the division lemma to get
32 = 22 x 1 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 462 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(32,22) = HCF(86,32) = HCF(376,86) = HCF(462,376) = HCF(838,462) .
