HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 71, 81, 69, 95 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 71, 81, 69, 95 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 71, 81, 69, 95 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 71, 81, 69, 95 is 1.
HCF(71, 81, 69, 95) = 1
HCF of 71, 81, 69, 95 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 71, 81, 69, 95 is 1.
Highest Common Factor of 71,81,69,95 is 1
Step 1: Since 81 > 71, we apply the division lemma to 81 and 71, to get
81 = 71 x 1 + 10
Step 2: Since the reminder 71 ≠ 0, we apply division lemma to 10 and 71, to get
71 = 10 x 7 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 71 and 81 is 1
Notice that 1 = HCF(10,1) = HCF(71,10) = HCF(81,71) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 69 > 1, we apply the division lemma to 69 and 1, to get
69 = 1 x 69 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 69 is 1
Notice that 1 = HCF(69,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 95 > 1, we apply the division lemma to 95 and 1, to get
95 = 1 x 95 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 95 is 1
Notice that 1 = HCF(95,1) .
