HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 217, 66549 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 217, 66549 is 7 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 217, 66549 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 217, 66549 is 7.
HCF(217, 66549) = 7
HCF of 217, 66549 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 217, 66549 is 7.
Highest Common Factor of 217,66549 is 7
Step 1: Since 66549 > 217, we apply the division lemma to 66549 and 217, to get
66549 = 217 x 306 + 147
Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 147 and 217, to get
217 = 147 x 1 + 70
Step 3: We consider the new divisor 147 and the new remainder 70, and apply the division lemma to get
147 = 70 x 2 + 7
We consider the new divisor 70 and the new remainder 7, and apply the division lemma to get
70 = 7 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 217 and 66549 is 7
Notice that 7 = HCF(70,7) = HCF(147,70) = HCF(217,147) = HCF(66549,217) .
