HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 895, 205, 497 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 895, 205, 497 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 895, 205, 497 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 895, 205, 497 is 1.
HCF(895, 205, 497) = 1
HCF of 895, 205, 497 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 895, 205, 497 is 1.
Highest Common Factor of 895,205,497 is 1
Step 1: Since 895 > 205, we apply the division lemma to 895 and 205, to get
895 = 205 x 4 + 75
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 75 and 205, to get
205 = 75 x 2 + 55
Step 3: We consider the new divisor 75 and the new remainder 55, and apply the division lemma to get
75 = 55 x 1 + 20
We consider the new divisor 55 and the new remainder 20,and apply the division lemma to get
55 = 20 x 2 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 895 and 205 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(55,20) = HCF(75,55) = HCF(205,75) = HCF(895,205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 497 > 5, we apply the division lemma to 497 and 5, to get
497 = 5 x 99 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 497 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(497,5) .
