HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 9966, 3079 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 9966, 3079 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 917, 9966, 3079 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 917, 9966, 3079 is 1.
HCF(917, 9966, 3079) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 9966, 3079 is 1.
Step 1: Since 9966 > 917, we apply the division lemma to 9966 and 917, to get
9966 = 917 x 10 + 796
Step 2: Since the reminder 917 ≠ 0, we apply division lemma to 796 and 917, to get
917 = 796 x 1 + 121
Step 3: We consider the new divisor 796 and the new remainder 121, and apply the division lemma to get
796 = 121 x 6 + 70
We consider the new divisor 121 and the new remainder 70,and apply the division lemma to get
121 = 70 x 1 + 51
We consider the new divisor 70 and the new remainder 51,and apply the division lemma to get
70 = 51 x 1 + 19
We consider the new divisor 51 and the new remainder 19,and apply the division lemma to get
51 = 19 x 2 + 13
We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get
19 = 13 x 1 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 9966 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(70,51) = HCF(121,70) = HCF(796,121) = HCF(917,796) = HCF(9966,917) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 3079 > 1, we apply the division lemma to 3079 and 1, to get
3079 = 1 x 3079 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 3079 is 1
Notice that 1 = HCF(3079,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
