HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 208, 819 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 208, 819 is 13 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 208, 819 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 208, 819 is 13.
HCF(208, 819) = 13
HCF of 208, 819 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 208, 819 is 13.
Highest Common Factor of 208,819 is 13
Step 1: Since 819 > 208, we apply the division lemma to 819 and 208, to get
819 = 208 x 3 + 195
Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 195 and 208, to get
208 = 195 x 1 + 13
Step 3: We consider the new divisor 195 and the new remainder 13, and apply the division lemma to get
195 = 13 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 208 and 819 is 13
Notice that 13 = HCF(195,13) = HCF(208,195) = HCF(819,208) .
