HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 52173 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 52173 is 3 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 798, 52173 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 798, 52173 is 3.
HCF(798, 52173) = 3
HCF of 798, 52173 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 798, 52173 is 3.
Highest Common Factor of 798,52173 is 3
Step 1: Since 52173 > 798, we apply the division lemma to 52173 and 798, to get
52173 = 798 x 65 + 303
Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 303 and 798, to get
798 = 303 x 2 + 192
Step 3: We consider the new divisor 303 and the new remainder 192, and apply the division lemma to get
303 = 192 x 1 + 111
We consider the new divisor 192 and the new remainder 111,and apply the division lemma to get
192 = 111 x 1 + 81
We consider the new divisor 111 and the new remainder 81,and apply the division lemma to get
111 = 81 x 1 + 30
We consider the new divisor 81 and the new remainder 30,and apply the division lemma to get
81 = 30 x 2 + 21
We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get
30 = 21 x 1 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 798 and 52173 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(81,30) = HCF(111,81) = HCF(192,111) = HCF(303,192) = HCF(798,303) = HCF(52173,798) .
