HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 677, 539 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 677, 539 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 816, 677, 539 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 816, 677, 539 is 1.
HCF(816, 677, 539) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 677, 539 is 1.
Step 1: Since 816 > 677, we apply the division lemma to 816 and 677, to get
816 = 677 x 1 + 139
Step 2: Since the reminder 677 ≠ 0, we apply division lemma to 139 and 677, to get
677 = 139 x 4 + 121
Step 3: We consider the new divisor 139 and the new remainder 121, and apply the division lemma to get
139 = 121 x 1 + 18
We consider the new divisor 121 and the new remainder 18,and apply the division lemma to get
121 = 18 x 6 + 13
We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get
18 = 13 x 1 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 816 and 677 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(121,18) = HCF(139,121) = HCF(677,139) = HCF(816,677) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 539 > 1, we apply the division lemma to 539 and 1, to get
539 = 1 x 539 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 539 is 1
Notice that 1 = HCF(539,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
