HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 863, 126, 382 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 863, 126, 382 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 863, 126, 382 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 863, 126, 382 is 1.
HCF(863, 126, 382) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 863, 126, 382 is 1.
Step 1: Since 863 > 126, we apply the division lemma to 863 and 126, to get
863 = 126 x 6 + 107
Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 107 and 126, to get
126 = 107 x 1 + 19
Step 3: We consider the new divisor 107 and the new remainder 19, and apply the division lemma to get
107 = 19 x 5 + 12
We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get
19 = 12 x 1 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 863 and 126 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(107,19) = HCF(126,107) = HCF(863,126) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 382 > 1, we apply the division lemma to 382 and 1, to get
382 = 1 x 382 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 382 is 1
Notice that 1 = HCF(382,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
