HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 386, 489 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 386, 489 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 386, 489 is 1.
HCF(386, 489) = 1
HCF of 386, 489 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 386, 489 is 1.
Highest Common Factor of 386,489 is 1
Step 1: Since 489 > 386, we apply the division lemma to 489 and 386, to get
489 = 386 x 1 + 103
Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 103 and 386, to get
386 = 103 x 3 + 77
Step 3: We consider the new divisor 103 and the new remainder 77, and apply the division lemma to get
103 = 77 x 1 + 26
We consider the new divisor 77 and the new remainder 26,and apply the division lemma to get
77 = 26 x 2 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 386 and 489 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(77,26) = HCF(103,77) = HCF(386,103) = HCF(489,386) .
