HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 287, 838, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 287, 838, 395 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 287, 838, 395 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 287, 838, 395 is 1.
HCF(287, 838, 395) = 1
HCF of 287, 838, 395 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 287, 838, 395 is 1.
Highest Common Factor of 287,838,395 is 1
Step 1: Since 838 > 287, we apply the division lemma to 838 and 287, to get
838 = 287 x 2 + 264
Step 2: Since the reminder 287 ≠ 0, we apply division lemma to 264 and 287, to get
287 = 264 x 1 + 23
Step 3: We consider the new divisor 264 and the new remainder 23, and apply the division lemma to get
264 = 23 x 11 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 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 287 and 838 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(264,23) = HCF(287,264) = HCF(838,287) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get
395 = 1 x 395 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1
Notice that 1 = HCF(395,1) .
