HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 864, 227 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 864, 227 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 820, 864, 227 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 820, 864, 227 is 1.
HCF(820, 864, 227) = 1
HCF of 820, 864, 227 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 864, 227 is 1.
Highest Common Factor of 820,864,227 is 1
Step 1: Since 864 > 820, we apply the division lemma to 864 and 820, to get
864 = 820 x 1 + 44
Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 44 and 820, to get
820 = 44 x 18 + 28
Step 3: We consider the new divisor 44 and the new remainder 28, and apply the division lemma to get
44 = 28 x 1 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 820 and 864 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(44,28) = HCF(820,44) = HCF(864,820) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 227 > 4, we apply the division lemma to 227 and 4, to get
227 = 4 x 56 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 4 and 227 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(227,4) .
