HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 188, 479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 188, 479 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 188, 479 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 188, 479 is 1.
HCF(188, 479) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 188, 479 is 1.
Step 1: Since 479 > 188, we apply the division lemma to 479 and 188, to get
479 = 188 x 2 + 103
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 103 and 188, to get
188 = 103 x 1 + 85
Step 3: We consider the new divisor 103 and the new remainder 85, and apply the division lemma to get
103 = 85 x 1 + 18
We consider the new divisor 85 and the new remainder 18,and apply the division lemma to get
85 = 18 x 4 + 13
We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get
18 = 13 x 1 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 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 188 and 479 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(85,18) = HCF(103,85) = HCF(188,103) = HCF(479,188) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 188, 479?
Answer: HCF of 188, 479 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 188, 479 using Euclid's Algorithm?
Answer: For arbitrary numbers 188, 479 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
