HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 869, 95 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 869, 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 717, 869, 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 717, 869, 95 is 1.
HCF(717, 869, 95) = 1
HCF of 717, 869, 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 717, 869, 95 is 1.
Highest Common Factor of 717,869,95 is 1
Step 1: Since 869 > 717, we apply the division lemma to 869 and 717, to get
869 = 717 x 1 + 152
Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 152 and 717, to get
717 = 152 x 4 + 109
Step 3: We consider the new divisor 152 and the new remainder 109, and apply the division lemma to get
152 = 109 x 1 + 43
We consider the new divisor 109 and the new remainder 43,and apply the division lemma to get
109 = 43 x 2 + 23
We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get
43 = 23 x 1 + 20
We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get
23 = 20 x 1 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 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 717 and 869 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(109,43) = HCF(152,109) = HCF(717,152) = HCF(869,717) .
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) .
