HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 419, 818 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 419, 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 419, 818 is 1.
HCF(419, 818) = 1
HCF of 419, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 419, 818 is 1.
Highest Common Factor of 419,818 is 1
Step 1: Since 818 > 419, we apply the division lemma to 818 and 419, to get
818 = 419 x 1 + 399
Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 399 and 419, to get
419 = 399 x 1 + 20
Step 3: We consider the new divisor 399 and the new remainder 20, and apply the division lemma to get
399 = 20 x 19 + 19
We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get
20 = 19 x 1 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 419 and 818 is 1
Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(399,20) = HCF(419,399) = HCF(818,419) .
