HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 815, 505, 110 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 815, 505, 110 is 5 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 815, 505, 110 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 815, 505, 110 is 5.
HCF(815, 505, 110) = 5
HCF of 815, 505, 110 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 815, 505, 110 is 5.
Highest Common Factor of 815,505,110 is 5
Step 1: Since 815 > 505, we apply the division lemma to 815 and 505, to get
815 = 505 x 1 + 310
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 310 and 505, to get
505 = 310 x 1 + 195
Step 3: We consider the new divisor 310 and the new remainder 195, and apply the division lemma to get
310 = 195 x 1 + 115
We consider the new divisor 195 and the new remainder 115,and apply the division lemma to get
195 = 115 x 1 + 80
We consider the new divisor 115 and the new remainder 80,and apply the division lemma to get
115 = 80 x 1 + 35
We consider the new divisor 80 and the new remainder 35,and apply the division lemma to get
80 = 35 x 2 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 815 and 505 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(80,35) = HCF(115,80) = HCF(195,115) = HCF(310,195) = HCF(505,310) = HCF(815,505) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 110 > 5, we apply the division lemma to 110 and 5, to get
110 = 5 x 22 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 110 is 5
Notice that 5 = HCF(110,5) .
