HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 603 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 668, 603 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 668, 603 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 668, 603 is 1.
HCF(668, 603) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 668, 603 is 1.
Step 1: Since 668 > 603, we apply the division lemma to 668 and 603, to get
668 = 603 x 1 + 65
Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 65 and 603, to get
603 = 65 x 9 + 18
Step 3: We consider the new divisor 65 and the new remainder 18, and apply the division lemma to get
65 = 18 x 3 + 11
We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get
18 = 11 x 1 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 668 and 603 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(65,18) = HCF(603,65) = HCF(668,603) .
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 668, 603?
Answer: HCF of 668, 603 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 668, 603 using Euclid's Algorithm?
Answer: For arbitrary numbers 668, 603 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
