HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 386, 272, 818 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 386, 272, 818 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 386, 272, 818 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, 272, 818 is 2.
HCF(386, 272, 818) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 386, 272, 818 is 2.
Step 1: Since 386 > 272, we apply the division lemma to 386 and 272, to get
386 = 272 x 1 + 114
Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 114 and 272, to get
272 = 114 x 2 + 44
Step 3: We consider the new divisor 114 and the new remainder 44, and apply the division lemma to get
114 = 44 x 2 + 26
We consider the new divisor 44 and the new remainder 26,and apply the division lemma to get
44 = 26 x 1 + 18
We consider the new divisor 26 and the new remainder 18,and apply the division lemma to get
26 = 18 x 1 + 8
We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 386 and 272 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(26,18) = HCF(44,26) = HCF(114,44) = HCF(272,114) = HCF(386,272) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 2, we apply the division lemma to 818 and 2, to get
818 = 2 x 409 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 818 is 2
Notice that 2 = HCF(818,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
