HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 212, 342, 162 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 212, 342, 162 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 212, 342, 162 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 212, 342, 162 is 2.
HCF(212, 342, 162) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 212, 342, 162 is 2.
Step 1: Since 342 > 212, we apply the division lemma to 342 and 212, to get
342 = 212 x 1 + 130
Step 2: Since the reminder 212 ≠ 0, we apply division lemma to 130 and 212, to get
212 = 130 x 1 + 82
Step 3: We consider the new divisor 130 and the new remainder 82, and apply the division lemma to get
130 = 82 x 1 + 48
We consider the new divisor 82 and the new remainder 48,and apply the division lemma to get
82 = 48 x 1 + 34
We consider the new divisor 48 and the new remainder 34,and apply the division lemma to get
48 = 34 x 1 + 14
We consider the new divisor 34 and the new remainder 14,and apply the division lemma to get
34 = 14 x 2 + 6
We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get
14 = 6 x 2 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 212 and 342 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(48,34) = HCF(82,48) = HCF(130,82) = HCF(212,130) = HCF(342,212) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 162 > 2, we apply the division lemma to 162 and 2, to get
162 = 2 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 162 is 2
Notice that 2 = HCF(162,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
