HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 847, 331, 826 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 847, 331, 826 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 847, 331, 826 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 847, 331, 826 is 1.
HCF(847, 331, 826) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 847, 331, 826 is 1.
Step 1: Since 847 > 331, we apply the division lemma to 847 and 331, to get
847 = 331 x 2 + 185
Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 185 and 331, to get
331 = 185 x 1 + 146
Step 3: We consider the new divisor 185 and the new remainder 146, and apply the division lemma to get
185 = 146 x 1 + 39
We consider the new divisor 146 and the new remainder 39,and apply the division lemma to get
146 = 39 x 3 + 29
We consider the new divisor 39 and the new remainder 29,and apply the division lemma to get
39 = 29 x 1 + 10
We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get
29 = 10 x 2 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 847 and 331 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(146,39) = HCF(185,146) = HCF(331,185) = HCF(847,331) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 826 > 1, we apply the division lemma to 826 and 1, to get
826 = 1 x 826 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 826 is 1
Notice that 1 = HCF(826,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
