HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 315, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 315, 845 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, 315, 845 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, 315, 845 is 1.
HCF(873, 315, 845) = 1
HCF of 873, 315, 845 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, 315, 845 is 1.
Highest Common Factor of 873,315,845 is 1
Step 1: Since 873 > 315, we apply the division lemma to 873 and 315, to get
873 = 315 x 2 + 243
Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 243 and 315, to get
315 = 243 x 1 + 72
Step 3: We consider the new divisor 243 and the new remainder 72, and apply the division lemma to get
243 = 72 x 3 + 27
We consider the new divisor 72 and the new remainder 27,and apply the division lemma to get
72 = 27 x 2 + 18
We consider the new divisor 27 and the new remainder 18,and apply the division lemma to get
27 = 18 x 1 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 873 and 315 is 9
Notice that 9 = HCF(18,9) = HCF(27,18) = HCF(72,27) = HCF(243,72) = HCF(315,243) = HCF(873,315) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 845 > 9, we apply the division lemma to 845 and 9, to get
845 = 9 x 93 + 8
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 8 and 9, to get
9 = 8 x 1 + 1
Step 3: We consider the new divisor 8 and the new remainder 1, and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 845 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(845,9) .
