HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 364, 515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 364, 515 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 585, 364, 515 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 585, 364, 515 is 1.
HCF(585, 364, 515) = 1
HCF of 585, 364, 515 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 364, 515 is 1.
Highest Common Factor of 585,364,515 is 1
Step 1: Since 585 > 364, we apply the division lemma to 585 and 364, to get
585 = 364 x 1 + 221
Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 221 and 364, to get
364 = 221 x 1 + 143
Step 3: We consider the new divisor 221 and the new remainder 143, and apply the division lemma to get
221 = 143 x 1 + 78
We consider the new divisor 143 and the new remainder 78,and apply the division lemma to get
143 = 78 x 1 + 65
We consider the new divisor 78 and the new remainder 65,and apply the division lemma to get
78 = 65 x 1 + 13
We consider the new divisor 65 and the new remainder 13,and apply the division lemma to get
65 = 13 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 585 and 364 is 13
Notice that 13 = HCF(65,13) = HCF(78,65) = HCF(143,78) = HCF(221,143) = HCF(364,221) = HCF(585,364) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 515 > 13, we apply the division lemma to 515 and 13, to get
515 = 13 x 39 + 8
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 8 and 13, to get
13 = 8 x 1 + 5
Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 13 and 515 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(515,13) .
