HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 866, 181, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 866, 181, 729 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 866, 181, 729 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 866, 181, 729 is 1.
HCF(866, 181, 729) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 866, 181, 729 is 1.
Step 1: Since 866 > 181, we apply the division lemma to 866 and 181, to get
866 = 181 x 4 + 142
Step 2: Since the reminder 181 ≠ 0, we apply division lemma to 142 and 181, to get
181 = 142 x 1 + 39
Step 3: We consider the new divisor 142 and the new remainder 39, and apply the division lemma to get
142 = 39 x 3 + 25
We consider the new divisor 39 and the new remainder 25,and apply the division lemma to get
39 = 25 x 1 + 14
We consider the new divisor 25 and the new remainder 14,and apply the division lemma to get
25 = 14 x 1 + 11
We consider the new divisor 14 and the new remainder 11,and apply the division lemma to get
14 = 11 x 1 + 3
We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get
11 = 3 x 3 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 866 and 181 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(25,14) = HCF(39,25) = HCF(142,39) = HCF(181,142) = HCF(866,181) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get
729 = 1 x 729 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1
Notice that 1 = HCF(729,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
