HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 681, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 681, 889 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 820, 681, 889 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 820, 681, 889 is 1.
HCF(820, 681, 889) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 681, 889 is 1.
Step 1: Since 820 > 681, we apply the division lemma to 820 and 681, to get
820 = 681 x 1 + 139
Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 139 and 681, to get
681 = 139 x 4 + 125
Step 3: We consider the new divisor 139 and the new remainder 125, and apply the division lemma to get
139 = 125 x 1 + 14
We consider the new divisor 125 and the new remainder 14,and apply the division lemma to get
125 = 14 x 8 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 681 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(125,14) = HCF(139,125) = HCF(681,139) = HCF(820,681) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 1, we apply the division lemma to 889 and 1, to get
889 = 1 x 889 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 889 is 1
Notice that 1 = HCF(889,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
