HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 317, 481, 670 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 317, 481, 670 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 317, 481, 670 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 317, 481, 670 is 1.
HCF(317, 481, 670) = 1
HCF of 317, 481, 670 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 317, 481, 670 is 1.
Highest Common Factor of 317,481,670 is 1
Step 1: Since 481 > 317, we apply the division lemma to 481 and 317, to get
481 = 317 x 1 + 164
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 164 and 317, to get
317 = 164 x 1 + 153
Step 3: We consider the new divisor 164 and the new remainder 153, and apply the division lemma to get
164 = 153 x 1 + 11
We consider the new divisor 153 and the new remainder 11,and apply the division lemma to get
153 = 11 x 13 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 317 and 481 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(153,11) = HCF(164,153) = HCF(317,164) = HCF(481,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 670 > 1, we apply the division lemma to 670 and 1, to get
670 = 1 x 670 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 670 is 1
Notice that 1 = HCF(670,1) .
