HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 626, 658 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 626, 658 is 2 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 626, 658 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 626, 658 is 2.
HCF(626, 658) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 626, 658 is 2.
Step 1: Since 658 > 626, we apply the division lemma to 658 and 626, to get
658 = 626 x 1 + 32
Step 2: Since the reminder 626 ≠ 0, we apply division lemma to 32 and 626, to get
626 = 32 x 19 + 18
Step 3: We consider the new divisor 32 and the new remainder 18, and apply the division lemma to get
32 = 18 x 1 + 14
We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get
18 = 14 x 1 + 4
We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get
14 = 4 x 3 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 626 and 658 is 2
Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(32,18) = HCF(626,32) = HCF(658,626) .
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 626, 658?
Answer: HCF of 626, 658 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 626, 658 using Euclid's Algorithm?
Answer: For arbitrary numbers 626, 658 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
