HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 695, 289, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 695, 289, 86 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 695, 289, 86 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 695, 289, 86 is 1.
HCF(695, 289, 86) = 1
HCF of 695, 289, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 695, 289, 86 is 1.
Highest Common Factor of 695,289,86 is 1
Step 1: Since 695 > 289, we apply the division lemma to 695 and 289, to get
695 = 289 x 2 + 117
Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 117 and 289, to get
289 = 117 x 2 + 55
Step 3: We consider the new divisor 117 and the new remainder 55, and apply the division lemma to get
117 = 55 x 2 + 7
We consider the new divisor 55 and the new remainder 7,and apply the division lemma to get
55 = 7 x 7 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 695 and 289 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(55,7) = HCF(117,55) = HCF(289,117) = HCF(695,289) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 1, we apply the division lemma to 86 and 1, to get
86 = 1 x 86 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 86 is 1
Notice that 1 = HCF(86,1) .
