HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 221, 4131 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 221, 4131 is 17 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, 4131 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, 4131 is 17.
HCF(221, 4131) = 17
HCF of 221, 4131 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, 4131 is 17.
Highest Common Factor of 221,4131 is 17
Step 1: Since 4131 > 221, we apply the division lemma to 4131 and 221, to get
4131 = 221 x 18 + 153
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 153 and 221, to get
221 = 153 x 1 + 68
Step 3: We consider the new divisor 153 and the new remainder 68, and apply the division lemma to get
153 = 68 x 2 + 17
We consider the new divisor 68 and the new remainder 17, and apply the division lemma to get
68 = 17 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 221 and 4131 is 17
Notice that 17 = HCF(68,17) = HCF(153,68) = HCF(221,153) = HCF(4131,221) .
