HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 740, 427 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 740, 427 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, 740, 427 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, 740, 427 is 1.
HCF(585, 740, 427) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 740, 427 is 1.
Step 1: Since 740 > 585, we apply the division lemma to 740 and 585, to get
740 = 585 x 1 + 155
Step 2: Since the reminder 585 ≠ 0, we apply division lemma to 155 and 585, to get
585 = 155 x 3 + 120
Step 3: We consider the new divisor 155 and the new remainder 120, and apply the division lemma to get
155 = 120 x 1 + 35
We consider the new divisor 120 and the new remainder 35,and apply the division lemma to get
120 = 35 x 3 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 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 585 and 740 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(120,35) = HCF(155,120) = HCF(585,155) = HCF(740,585) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 427 > 5, we apply the division lemma to 427 and 5, to get
427 = 5 x 85 + 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 427 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(427,5) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 585, 740, 427?
Answer: HCF of 585, 740, 427 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 585, 740, 427 using Euclid's Algorithm?
