HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 979, 563, 95 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 979, 563, 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 831, 979, 563, 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 831, 979, 563, 95 is 1.
HCF(831, 979, 563, 95) = 1
HCF of 831, 979, 563, 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 831, 979, 563, 95 is 1.
Highest Common Factor of 831,979,563,95 is 1
Step 1: Since 979 > 831, we apply the division lemma to 979 and 831, to get
979 = 831 x 1 + 148
Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 148 and 831, to get
831 = 148 x 5 + 91
Step 3: We consider the new divisor 148 and the new remainder 91, and apply the division lemma to get
148 = 91 x 1 + 57
We consider the new divisor 91 and the new remainder 57,and apply the division lemma to get
91 = 57 x 1 + 34
We consider the new divisor 57 and the new remainder 34,and apply the division lemma to get
57 = 34 x 1 + 23
We consider the new divisor 34 and the new remainder 23,and apply the division lemma to get
34 = 23 x 1 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 831 and 979 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(34,23) = HCF(57,34) = HCF(91,57) = HCF(148,91) = HCF(831,148) = HCF(979,831) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 563 > 1, we apply the division lemma to 563 and 1, to get
563 = 1 x 563 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 563 is 1
Notice that 1 = HCF(563,1) .
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) .
