HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 711, 396, 208 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 711, 396, 208 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 711, 396, 208 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 711, 396, 208 is 1.
HCF(711, 396, 208) = 1
HCF of 711, 396, 208 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 711, 396, 208 is 1.
Highest Common Factor of 711,396,208 is 1
Step 1: Since 711 > 396, we apply the division lemma to 711 and 396, to get
711 = 396 x 1 + 315
Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 315 and 396, to get
396 = 315 x 1 + 81
Step 3: We consider the new divisor 315 and the new remainder 81, and apply the division lemma to get
315 = 81 x 3 + 72
We consider the new divisor 81 and the new remainder 72,and apply the division lemma to get
81 = 72 x 1 + 9
We consider the new divisor 72 and the new remainder 9,and apply the division lemma to get
72 = 9 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 711 and 396 is 9
Notice that 9 = HCF(72,9) = HCF(81,72) = HCF(315,81) = HCF(396,315) = HCF(711,396) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 208 > 9, we apply the division lemma to 208 and 9, to get
208 = 9 x 23 + 1
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 1 and 9, to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9 and 208 is 1
Notice that 1 = HCF(9,1) = HCF(208,9) .
