HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 301, 418, 122, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 301, 418, 122, 66 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 301, 418, 122, 66 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 301, 418, 122, 66 is 1.
HCF(301, 418, 122, 66) = 1
HCF of 301, 418, 122, 66 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 301, 418, 122, 66 is 1.
Highest Common Factor of 301,418,122,66 is 1
Step 1: Since 418 > 301, we apply the division lemma to 418 and 301, to get
418 = 301 x 1 + 117
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 117 and 301, to get
301 = 117 x 2 + 67
Step 3: We consider the new divisor 117 and the new remainder 67, and apply the division lemma to get
117 = 67 x 1 + 50
We consider the new divisor 67 and the new remainder 50,and apply the division lemma to get
67 = 50 x 1 + 17
We consider the new divisor 50 and the new remainder 17,and apply the division lemma to get
50 = 17 x 2 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 301 and 418 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(50,17) = HCF(67,50) = HCF(117,67) = HCF(301,117) = HCF(418,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 122 > 1, we apply the division lemma to 122 and 1, to get
122 = 1 x 122 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 122 is 1
Notice that 1 = HCF(122,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get
66 = 1 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1
Notice that 1 = HCF(66,1) .
