HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 817, 349 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 817, 349 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 817, 349 is 1.
HCF(817, 349) = 1
HCF of 817, 349 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 817, 349 is 1.
Highest Common Factor of 817,349 is 1
Step 1: Since 817 > 349, we apply the division lemma to 817 and 349, to get
817 = 349 x 2 + 119
Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 119 and 349, to get
349 = 119 x 2 + 111
Step 3: We consider the new divisor 119 and the new remainder 111, and apply the division lemma to get
119 = 111 x 1 + 8
We consider the new divisor 111 and the new remainder 8,and apply the division lemma to get
111 = 8 x 13 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 817 and 349 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(111,8) = HCF(119,111) = HCF(349,119) = HCF(817,349) .
