HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 221 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 221 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 493, 221 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 493, 221 is 17.
HCF(493, 221) = 17
HCF of 493, 221 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 221 is 17.
Highest Common Factor of 493,221 is 17
Step 1: Since 493 > 221, we apply the division lemma to 493 and 221, to get
493 = 221 x 2 + 51
Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 51 and 221, to get
221 = 51 x 4 + 17
Step 3: We consider the new divisor 51 and the new remainder 17, and apply the division lemma to get
51 = 17 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 493 and 221 is 17
Notice that 17 = HCF(51,17) = HCF(221,51) = HCF(493,221) .
