HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 162, 243, 301 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 162, 243, 301 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 162, 243, 301 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 162, 243, 301 is 1.
HCF(162, 243, 301) = 1
HCF of 162, 243, 301 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 162, 243, 301 is 1.
Highest Common Factor of 162,243,301 is 1
Step 1: Since 243 > 162, we apply the division lemma to 243 and 162, to get
243 = 162 x 1 + 81
Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 81 and 162, to get
162 = 81 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 81, the HCF of 162 and 243 is 81
Notice that 81 = HCF(162,81) = HCF(243,162) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 301 > 81, we apply the division lemma to 301 and 81, to get
301 = 81 x 3 + 58
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 58 and 81, to get
81 = 58 x 1 + 23
Step 3: We consider the new divisor 58 and the new remainder 23, and apply the division lemma to get
58 = 23 x 2 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 81 and 301 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(58,23) = HCF(81,58) = HCF(301,81) .
