HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 709, 317, 475, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 709, 317, 475, 12 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 709, 317, 475, 12 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 709, 317, 475, 12 is 1.
HCF(709, 317, 475, 12) = 1
HCF of 709, 317, 475, 12 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 709, 317, 475, 12 is 1.
Highest Common Factor of 709,317,475,12 is 1
Step 1: Since 709 > 317, we apply the division lemma to 709 and 317, to get
709 = 317 x 2 + 75
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 75 and 317, to get
317 = 75 x 4 + 17
Step 3: We consider the new divisor 75 and the new remainder 17, and apply the division lemma to get
75 = 17 x 4 + 7
We consider the new divisor 17 and the new remainder 7,and apply the division lemma to get
17 = 7 x 2 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 709 and 317 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(17,7) = HCF(75,17) = HCF(317,75) = HCF(709,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 1, we apply the division lemma to 475 and 1, to get
475 = 1 x 475 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 475 is 1
Notice that 1 = HCF(475,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
