HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 119, 811 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 408, 119, 811 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 408, 119, 811 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 408, 119, 811 is 1.
HCF(408, 119, 811) = 1
HCF of 408, 119, 811 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 408, 119, 811 is 1.
Highest Common Factor of 408,119,811 is 1
Step 1: Since 408 > 119, we apply the division lemma to 408 and 119, to get
408 = 119 x 3 + 51
Step 2: Since the reminder 119 ≠ 0, we apply division lemma to 51 and 119, to get
119 = 51 x 2 + 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 408 and 119 is 17
Notice that 17 = HCF(51,17) = HCF(119,51) = HCF(408,119) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 811 > 17, we apply the division lemma to 811 and 17, to get
811 = 17 x 47 + 12
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 12 and 17, to get
17 = 12 x 1 + 5
Step 3: We consider the new divisor 12 and the new remainder 5, and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 811 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(811,17) .
