HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 793, 838, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 793, 838, 285 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 793, 838, 285 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 793, 838, 285 is 1.
HCF(793, 838, 285) = 1
HCF of 793, 838, 285 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 793, 838, 285 is 1.
Highest Common Factor of 793,838,285 is 1
Step 1: Since 838 > 793, we apply the division lemma to 838 and 793, to get
838 = 793 x 1 + 45
Step 2: Since the reminder 793 ≠ 0, we apply division lemma to 45 and 793, to get
793 = 45 x 17 + 28
Step 3: We consider the new divisor 45 and the new remainder 28, and apply the division lemma to get
45 = 28 x 1 + 17
We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get
28 = 17 x 1 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 793 and 838 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(45,28) = HCF(793,45) = HCF(838,793) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 285 > 1, we apply the division lemma to 285 and 1, to get
285 = 1 x 285 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 285 is 1
Notice that 1 = HCF(285,1) .
