HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 231, 786, 466 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 231, 786, 466 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 231, 786, 466 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 231, 786, 466 is 1.
HCF(231, 786, 466) = 1
HCF of 231, 786, 466 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 231, 786, 466 is 1.
Highest Common Factor of 231,786,466 is 1
Step 1: Since 786 > 231, we apply the division lemma to 786 and 231, to get
786 = 231 x 3 + 93
Step 2: Since the reminder 231 ≠ 0, we apply division lemma to 93 and 231, to get
231 = 93 x 2 + 45
Step 3: We consider the new divisor 93 and the new remainder 45, and apply the division lemma to get
93 = 45 x 2 + 3
We consider the new divisor 45 and the new remainder 3, and apply the division lemma to get
45 = 3 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 231 and 786 is 3
Notice that 3 = HCF(45,3) = HCF(93,45) = HCF(231,93) = HCF(786,231) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 466 > 3, we apply the division lemma to 466 and 3, to get
466 = 3 x 155 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 466 is 1
Notice that 1 = HCF(3,1) = HCF(466,3) .
