HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 856, 865, 696 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 856, 865, 696 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 819, 856, 865, 696 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 819, 856, 865, 696 is 1.
HCF(819, 856, 865, 696) = 1
HCF of 819, 856, 865, 696 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 856, 865, 696 is 1.
Highest Common Factor of 819,856,865,696 is 1
Step 1: Since 856 > 819, we apply the division lemma to 856 and 819, to get
856 = 819 x 1 + 37
Step 2: Since the reminder 819 ≠ 0, we apply division lemma to 37 and 819, to get
819 = 37 x 22 + 5
Step 3: We consider the new divisor 37 and the new remainder 5, and apply the division lemma to get
37 = 5 x 7 + 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 819 and 856 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(819,37) = HCF(856,819) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 865 > 1, we apply the division lemma to 865 and 1, to get
865 = 1 x 865 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 865 is 1
Notice that 1 = HCF(865,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 696 > 1, we apply the division lemma to 696 and 1, to get
696 = 1 x 696 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 696 is 1
Notice that 1 = HCF(696,1) .
