HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 474, 465 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 474, 465 is 3 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, 474, 465 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, 474, 465 is 3.
HCF(585, 474, 465) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 474, 465 is 3.
Step 1: Since 585 > 474, we apply the division lemma to 585 and 474, to get
585 = 474 x 1 + 111
Step 2: Since the reminder 474 ≠ 0, we apply division lemma to 111 and 474, to get
474 = 111 x 4 + 30
Step 3: We consider the new divisor 111 and the new remainder 30, and apply the division lemma to get
111 = 30 x 3 + 21
We consider the new divisor 30 and the new remainder 21,and apply the division lemma to get
30 = 21 x 1 + 9
We consider the new divisor 21 and the new remainder 9,and apply the division lemma to get
21 = 9 x 2 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 585 and 474 is 3
Notice that 3 = HCF(9,3) = HCF(21,9) = HCF(30,21) = HCF(111,30) = HCF(474,111) = HCF(585,474) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 465 > 3, we apply the division lemma to 465 and 3, to get
465 = 3 x 155 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 465 is 3
Notice that 3 = HCF(465,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 585, 474, 465?
Answer: HCF of 585, 474, 465 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 585, 474, 465 using Euclid's Algorithm?
Answer: For arbitrary numbers 585, 474, 465 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
