HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 818, 306 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 818, 306 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 818, 306 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 818, 306 is 2.
HCF(818, 306) = 2
HCF of 818, 306 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 818, 306 is 2.
Highest Common Factor of 818,306 is 2
Step 1: Since 818 > 306, we apply the division lemma to 818 and 306, to get
818 = 306 x 2 + 206
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 206 and 306, to get
306 = 206 x 1 + 100
Step 3: We consider the new divisor 206 and the new remainder 100, and apply the division lemma to get
206 = 100 x 2 + 6
We consider the new divisor 100 and the new remainder 6,and apply the division lemma to get
100 = 6 x 16 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 818 and 306 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(100,6) = HCF(206,100) = HCF(306,206) = HCF(818,306) .
