HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 680, 811, 511 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 680, 811, 511 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 680, 811, 511 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 680, 811, 511 is 1.
HCF(680, 811, 511) = 1
HCF of 680, 811, 511 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 680, 811, 511 is 1.
Highest Common Factor of 680,811,511 is 1
Step 1: Since 811 > 680, we apply the division lemma to 811 and 680, to get
811 = 680 x 1 + 131
Step 2: Since the reminder 680 ≠ 0, we apply division lemma to 131 and 680, to get
680 = 131 x 5 + 25
Step 3: We consider the new divisor 131 and the new remainder 25, and apply the division lemma to get
131 = 25 x 5 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 680 and 811 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(131,25) = HCF(680,131) = HCF(811,680) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 511 > 1, we apply the division lemma to 511 and 1, to get
511 = 1 x 511 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 511 is 1
Notice that 1 = HCF(511,1) .
