HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 829, 793 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 397, 829, 793 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 397, 829, 793 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 397, 829, 793 is 1.
HCF(397, 829, 793) = 1
HCF of 397, 829, 793 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 397, 829, 793 is 1.
Highest Common Factor of 397,829,793 is 1
Step 1: Since 829 > 397, we apply the division lemma to 829 and 397, to get
829 = 397 x 2 + 35
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 35 and 397, to get
397 = 35 x 11 + 12
Step 3: We consider the new divisor 35 and the new remainder 12, and apply the division lemma to get
35 = 12 x 2 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 829 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(397,35) = HCF(829,397) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 793 > 1, we apply the division lemma to 793 and 1, to get
793 = 1 x 793 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 793 is 1
Notice that 1 = HCF(793,1) .
