HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 878, 335 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 878, 335 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 689, 878, 335 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 689, 878, 335 is 1.
HCF(689, 878, 335) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 878, 335 is 1.
Step 1: Since 878 > 689, we apply the division lemma to 878 and 689, to get
878 = 689 x 1 + 189
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 189 and 689, to get
689 = 189 x 3 + 122
Step 3: We consider the new divisor 189 and the new remainder 122, and apply the division lemma to get
189 = 122 x 1 + 67
We consider the new divisor 122 and the new remainder 67,and apply the division lemma to get
122 = 67 x 1 + 55
We consider the new divisor 67 and the new remainder 55,and apply the division lemma to get
67 = 55 x 1 + 12
We consider the new divisor 55 and the new remainder 12,and apply the division lemma to get
55 = 12 x 4 + 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 689 and 878 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(55,12) = HCF(67,55) = HCF(122,67) = HCF(189,122) = HCF(689,189) = HCF(878,689) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 335 > 1, we apply the division lemma to 335 and 1, to get
335 = 1 x 335 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 335 is 1
Notice that 1 = HCF(335,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
