HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 688, 206 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 688, 206 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 417, 688, 206 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 417, 688, 206 is 1.
HCF(417, 688, 206) = 1
HCF of 417, 688, 206 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 417, 688, 206 is 1.
Highest Common Factor of 417,688,206 is 1
Step 1: Since 688 > 417, we apply the division lemma to 688 and 417, to get
688 = 417 x 1 + 271
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 271 and 417, to get
417 = 271 x 1 + 146
Step 3: We consider the new divisor 271 and the new remainder 146, and apply the division lemma to get
271 = 146 x 1 + 125
We consider the new divisor 146 and the new remainder 125,and apply the division lemma to get
146 = 125 x 1 + 21
We consider the new divisor 125 and the new remainder 21,and apply the division lemma to get
125 = 21 x 5 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 417 and 688 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(125,21) = HCF(146,125) = HCF(271,146) = HCF(417,271) = HCF(688,417) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 206 > 1, we apply the division lemma to 206 and 1, to get
206 = 1 x 206 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 206 is 1
Notice that 1 = HCF(206,1) .
