HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 326, 10 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 326, 10 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 857, 326, 10 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 857, 326, 10 is 1.
HCF(857, 326, 10) = 1
HCF of 857, 326, 10 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 326, 10 is 1.
Highest Common Factor of 857,326,10 is 1
Step 1: Since 857 > 326, we apply the division lemma to 857 and 326, to get
857 = 326 x 2 + 205
Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 205 and 326, to get
326 = 205 x 1 + 121
Step 3: We consider the new divisor 205 and the new remainder 121, and apply the division lemma to get
205 = 121 x 1 + 84
We consider the new divisor 121 and the new remainder 84,and apply the division lemma to get
121 = 84 x 1 + 37
We consider the new divisor 84 and the new remainder 37,and apply the division lemma to get
84 = 37 x 2 + 10
We consider the new divisor 37 and the new remainder 10,and apply the division lemma to get
37 = 10 x 3 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 857 and 326 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(37,10) = HCF(84,37) = HCF(121,84) = HCF(205,121) = HCF(326,205) = HCF(857,326) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 10 > 1, we apply the division lemma to 10 and 1, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 10 is 1
Notice that 1 = HCF(10,1) .
