HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 301, 455, 331 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 301, 455, 331 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, 455, 331 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, 455, 331 is 1.
HCF(301, 455, 331) = 1
HCF of 301, 455, 331 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, 455, 331 is 1.
Highest Common Factor of 301,455,331 is 1
Step 1: Since 455 > 301, we apply the division lemma to 455 and 301, to get
455 = 301 x 1 + 154
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 154 and 301, to get
301 = 154 x 1 + 147
Step 3: We consider the new divisor 154 and the new remainder 147, and apply the division lemma to get
154 = 147 x 1 + 7
We consider the new divisor 147 and the new remainder 7, and apply the division lemma to get
147 = 7 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 301 and 455 is 7
Notice that 7 = HCF(147,7) = HCF(154,147) = HCF(301,154) = HCF(455,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 331 > 7, we apply the division lemma to 331 and 7, to get
331 = 7 x 47 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 331 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(331,7) .
