HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 873 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 393, 873 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 393, 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 393, 873 is 3.
HCF(393, 873) = 3
HCF of 393, 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 393, 873 is 3.
Highest Common Factor of 393,873 is 3
Step 1: Since 873 > 393, we apply the division lemma to 873 and 393, to get
873 = 393 x 2 + 87
Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 87 and 393, to get
393 = 87 x 4 + 45
Step 3: We consider the new divisor 87 and the new remainder 45, and apply the division lemma to get
87 = 45 x 1 + 42
We consider the new divisor 45 and the new remainder 42,and apply the division lemma to get
45 = 42 x 1 + 3
We consider the new divisor 42 and the new remainder 3,and apply the division lemma to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 393 and 873 is 3
Notice that 3 = HCF(42,3) = HCF(45,42) = HCF(87,45) = HCF(393,87) = HCF(873,393) .
