HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 188, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 188, 669 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, 669 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, 669 is 1.
HCF(188, 669) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 188, 669 is 1.
Step 1: Since 669 > 188, we apply the division lemma to 669 and 188, to get
669 = 188 x 3 + 105
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 105 and 188, to get
188 = 105 x 1 + 83
Step 3: We consider the new divisor 105 and the new remainder 83, and apply the division lemma to get
105 = 83 x 1 + 22
We consider the new divisor 83 and the new remainder 22,and apply the division lemma to get
83 = 22 x 3 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 669 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(83,22) = HCF(105,83) = HCF(188,105) = HCF(669,188) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 188, 669?
Answer: HCF of 188, 669 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 188, 669 using Euclid's Algorithm?
Answer: For arbitrary numbers 188, 669 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
