HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 329, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 329, 815 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 505, 329, 815 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 505, 329, 815 is 1.
HCF(505, 329, 815) = 1
HCF of 505, 329, 815 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 329, 815 is 1.
Highest Common Factor of 505,329,815 is 1
Step 1: Since 505 > 329, we apply the division lemma to 505 and 329, to get
505 = 329 x 1 + 176
Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 176 and 329, to get
329 = 176 x 1 + 153
Step 3: We consider the new divisor 176 and the new remainder 153, and apply the division lemma to get
176 = 153 x 1 + 23
We consider the new divisor 153 and the new remainder 23,and apply the division lemma to get
153 = 23 x 6 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 505 and 329 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(153,23) = HCF(176,153) = HCF(329,176) = HCF(505,329) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 815 > 1, we apply the division lemma to 815 and 1, to get
815 = 1 x 815 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 815 is 1
Notice that 1 = HCF(815,1) .
