HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 528, 943 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 528, 943 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 873, 528, 943 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 873, 528, 943 is 1.
HCF(873, 528, 943) = 1
HCF of 873, 528, 943 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 873, 528, 943 is 1.
Highest Common Factor of 873,528,943 is 1
Step 1: Since 873 > 528, we apply the division lemma to 873 and 528, to get
873 = 528 x 1 + 345
Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 345 and 528, to get
528 = 345 x 1 + 183
Step 3: We consider the new divisor 345 and the new remainder 183, and apply the division lemma to get
345 = 183 x 1 + 162
We consider the new divisor 183 and the new remainder 162,and apply the division lemma to get
183 = 162 x 1 + 21
We consider the new divisor 162 and the new remainder 21,and apply the division lemma to get
162 = 21 x 7 + 15
We consider the new divisor 21 and the new remainder 15,and apply the division lemma to get
21 = 15 x 1 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 873 and 528 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(21,15) = HCF(162,21) = HCF(183,162) = HCF(345,183) = HCF(528,345) = HCF(873,528) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 943 > 3, we apply the division lemma to 943 and 3, to get
943 = 3 x 314 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 943 is 1
Notice that 1 = HCF(3,1) = HCF(943,3) .
