HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 349, 9986 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 349, 9986 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 349, 9986 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 349, 9986 is 1.
HCF(349, 9986) = 1
HCF of 349, 9986 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 349, 9986 is 1.
Highest Common Factor of 349,9986 is 1
Step 1: Since 9986 > 349, we apply the division lemma to 9986 and 349, to get
9986 = 349 x 28 + 214
Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 214 and 349, to get
349 = 214 x 1 + 135
Step 3: We consider the new divisor 214 and the new remainder 135, and apply the division lemma to get
214 = 135 x 1 + 79
We consider the new divisor 135 and the new remainder 79,and apply the division lemma to get
135 = 79 x 1 + 56
We consider the new divisor 79 and the new remainder 56,and apply the division lemma to get
79 = 56 x 1 + 23
We consider the new divisor 56 and the new remainder 23,and apply the division lemma to get
56 = 23 x 2 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 349 and 9986 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(56,23) = HCF(79,56) = HCF(135,79) = HCF(214,135) = HCF(349,214) = HCF(9986,349) .
