HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 816, 227, 864 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 816, 227, 864 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 816, 227, 864 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 816, 227, 864 is 1.
HCF(816, 227, 864) = 1
HCF of 816, 227, 864 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 816, 227, 864 is 1.
Highest Common Factor of 816,227,864 is 1
Step 1: Since 816 > 227, we apply the division lemma to 816 and 227, to get
816 = 227 x 3 + 135
Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 135 and 227, to get
227 = 135 x 1 + 92
Step 3: We consider the new divisor 135 and the new remainder 92, and apply the division lemma to get
135 = 92 x 1 + 43
We consider the new divisor 92 and the new remainder 43,and apply the division lemma to get
92 = 43 x 2 + 6
We consider the new divisor 43 and the new remainder 6,and apply the division lemma to get
43 = 6 x 7 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 816 and 227 is 1
Notice that 1 = HCF(6,1) = HCF(43,6) = HCF(92,43) = HCF(135,92) = HCF(227,135) = HCF(816,227) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 864 > 1, we apply the division lemma to 864 and 1, to get
864 = 1 x 864 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 864 is 1
Notice that 1 = HCF(864,1) .
