HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 191, 546 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 311, 191, 546 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 311, 191, 546 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 311, 191, 546 is 1.
HCF(311, 191, 546) = 1
HCF of 311, 191, 546 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 311, 191, 546 is 1.
Highest Common Factor of 311,191,546 is 1
Step 1: Since 311 > 191, we apply the division lemma to 311 and 191, to get
311 = 191 x 1 + 120
Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 120 and 191, to get
191 = 120 x 1 + 71
Step 3: We consider the new divisor 120 and the new remainder 71, and apply the division lemma to get
120 = 71 x 1 + 49
We consider the new divisor 71 and the new remainder 49,and apply the division lemma to get
71 = 49 x 1 + 22
We consider the new divisor 49 and the new remainder 22,and apply the division lemma to get
49 = 22 x 2 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 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 311 and 191 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(49,22) = HCF(71,49) = HCF(120,71) = HCF(191,120) = HCF(311,191) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 546 > 1, we apply the division lemma to 546 and 1, to get
546 = 1 x 546 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 546 is 1
Notice that 1 = HCF(546,1) .
