HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 867, 229, 191 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 221, 867, 229, 191 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 221, 867, 229, 191 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 221, 867, 229, 191 is 1.
HCF(221, 867, 229, 191) = 1
HCF of 221, 867, 229, 191 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 221, 867, 229, 191 is 1.
Highest Common Factor of 221,867,229,191 is 1
Step 1: Since 867 > 221, we apply the division lemma to 867 and 221, to get
867 = 221 x 3 + 204
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 204 and 221, to get
221 = 204 x 1 + 17
Step 3: We consider the new divisor 204 and the new remainder 17, and apply the division lemma to get
204 = 17 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 221 and 867 is 17
Notice that 17 = HCF(204,17) = HCF(221,204) = HCF(867,221) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 229 > 17, we apply the division lemma to 229 and 17, to get
229 = 17 x 13 + 8
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 8 and 17, to get
17 = 8 x 2 + 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 17 and 229 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(229,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 191 > 1, we apply the division lemma to 191 and 1, to get
191 = 1 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 191 is 1
Notice that 1 = HCF(191,1) .
