HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 4019, 470 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 4019, 470 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 4019, 470 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 4019, 470 is 1.
HCF(4019, 470) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 4019, 470 is 1.
Step 1: Since 4019 > 470, we apply the division lemma to 4019 and 470, to get
4019 = 470 x 8 + 259
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 259 and 470, to get
470 = 259 x 1 + 211
Step 3: We consider the new divisor 259 and the new remainder 211, and apply the division lemma to get
259 = 211 x 1 + 48
We consider the new divisor 211 and the new remainder 48,and apply the division lemma to get
211 = 48 x 4 + 19
We consider the new divisor 48 and the new remainder 19,and apply the division lemma to get
48 = 19 x 2 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4019 and 470 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(48,19) = HCF(211,48) = HCF(259,211) = HCF(470,259) = HCF(4019,470) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 4019, 470?
Answer: HCF of 4019, 470 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 4019, 470 using Euclid's Algorithm?
Answer: For arbitrary numbers 4019, 470 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
