HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 811, 111 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 811, 111 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 620, 811, 111 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 620, 811, 111 is 1.
HCF(620, 811, 111) = 1
HCF of 620, 811, 111 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 811, 111 is 1.
Highest Common Factor of 620,811,111 is 1
Step 1: Since 811 > 620, we apply the division lemma to 811 and 620, to get
811 = 620 x 1 + 191
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 191 and 620, to get
620 = 191 x 3 + 47
Step 3: We consider the new divisor 191 and the new remainder 47, and apply the division lemma to get
191 = 47 x 4 + 3
We consider the new divisor 47 and the new remainder 3,and apply the division lemma to get
47 = 3 x 15 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 620 and 811 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(191,47) = HCF(620,191) = HCF(811,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 111 > 1, we apply the division lemma to 111 and 1, to get
111 = 1 x 111 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 111 is 1
Notice that 1 = HCF(111,1) .
