HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 466, 294, 816 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 466, 294, 816 is 2 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 466, 294, 816 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 466, 294, 816 is 2.
HCF(466, 294, 816) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 466, 294, 816 is 2.
Step 1: Since 466 > 294, we apply the division lemma to 466 and 294, to get
466 = 294 x 1 + 172
Step 2: Since the reminder 294 ≠ 0, we apply division lemma to 172 and 294, to get
294 = 172 x 1 + 122
Step 3: We consider the new divisor 172 and the new remainder 122, and apply the division lemma to get
172 = 122 x 1 + 50
We consider the new divisor 122 and the new remainder 50,and apply the division lemma to get
122 = 50 x 2 + 22
We consider the new divisor 50 and the new remainder 22,and apply the division lemma to get
50 = 22 x 2 + 6
We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get
22 = 6 x 3 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 466 and 294 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(50,22) = HCF(122,50) = HCF(172,122) = HCF(294,172) = HCF(466,294) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 816 > 2, we apply the division lemma to 816 and 2, to get
816 = 2 x 408 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 816 is 2
Notice that 2 = HCF(816,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
