HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 386 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 493, 386 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 493, 386 is 1.
HCF(493, 386) = 1
HCF of 493, 386 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 386 is 1.
Highest Common Factor of 493,386 is 1
Step 1: Since 493 > 386, we apply the division lemma to 493 and 386, to get
493 = 386 x 1 + 107
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 107 and 386, to get
386 = 107 x 3 + 65
Step 3: We consider the new divisor 107 and the new remainder 65, and apply the division lemma to get
107 = 65 x 1 + 42
We consider the new divisor 65 and the new remainder 42,and apply the division lemma to get
65 = 42 x 1 + 23
We consider the new divisor 42 and the new remainder 23,and apply the division lemma to get
42 = 23 x 1 + 19
We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get
23 = 19 x 1 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 386 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(42,23) = HCF(65,42) = HCF(107,65) = HCF(386,107) = HCF(493,386) .
