HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 608, 343 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 817, 608, 343 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 817, 608, 343 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 817, 608, 343 is 1.
HCF(817, 608, 343) = 1
HCF of 817, 608, 343 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 817, 608, 343 is 1.
Highest Common Factor of 817,608,343 is 1
Step 1: Since 817 > 608, we apply the division lemma to 817 and 608, to get
817 = 608 x 1 + 209
Step 2: Since the reminder 608 ≠ 0, we apply division lemma to 209 and 608, to get
608 = 209 x 2 + 190
Step 3: We consider the new divisor 209 and the new remainder 190, and apply the division lemma to get
209 = 190 x 1 + 19
We consider the new divisor 190 and the new remainder 19, and apply the division lemma to get
190 = 19 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 817 and 608 is 19
Notice that 19 = HCF(190,19) = HCF(209,190) = HCF(608,209) = HCF(817,608) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 343 > 19, we apply the division lemma to 343 and 19, to get
343 = 19 x 18 + 1
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 1 and 19, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 343 is 1
Notice that 1 = HCF(19,1) = HCF(343,19) .
