HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 205, 873 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 979, 205, 873 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 979, 205, 873 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 979, 205, 873 is 1.
HCF(979, 205, 873) = 1
HCF of 979, 205, 873 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 979, 205, 873 is 1.
Highest Common Factor of 979,205,873 is 1
Step 1: Since 979 > 205, we apply the division lemma to 979 and 205, to get
979 = 205 x 4 + 159
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 159 and 205, to get
205 = 159 x 1 + 46
Step 3: We consider the new divisor 159 and the new remainder 46, and apply the division lemma to get
159 = 46 x 3 + 21
We consider the new divisor 46 and the new remainder 21,and apply the division lemma to get
46 = 21 x 2 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 979 and 205 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(46,21) = HCF(159,46) = HCF(205,159) = HCF(979,205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 873 > 1, we apply the division lemma to 873 and 1, to get
873 = 1 x 873 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 873 is 1
Notice that 1 = HCF(873,1) .
