HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 704, 317, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 704, 317, 781 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 704, 317, 781 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 704, 317, 781 is 1.
HCF(704, 317, 781) = 1
HCF of 704, 317, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 704, 317, 781 is 1.
Highest Common Factor of 704,317,781 is 1
Step 1: Since 704 > 317, we apply the division lemma to 704 and 317, to get
704 = 317 x 2 + 70
Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 70 and 317, to get
317 = 70 x 4 + 37
Step 3: We consider the new divisor 70 and the new remainder 37, and apply the division lemma to get
70 = 37 x 1 + 33
We consider the new divisor 37 and the new remainder 33,and apply the division lemma to get
37 = 33 x 1 + 4
We consider the new divisor 33 and the new remainder 4,and apply the division lemma to get
33 = 4 x 8 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 704 and 317 is 1
Notice that 1 = HCF(4,1) = HCF(33,4) = HCF(37,33) = HCF(70,37) = HCF(317,70) = HCF(704,317) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 1, we apply the division lemma to 781 and 1, to get
781 = 1 x 781 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 781 is 1
Notice that 1 = HCF(781,1) .
