HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 626 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 626 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 494, 626 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 494, 626 is 2.
HCF(494, 626) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 494, 626 is 2.
Step 1: Since 626 > 494, we apply the division lemma to 626 and 494, to get
626 = 494 x 1 + 132
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 132 and 494, to get
494 = 132 x 3 + 98
Step 3: We consider the new divisor 132 and the new remainder 98, and apply the division lemma to get
132 = 98 x 1 + 34
We consider the new divisor 98 and the new remainder 34,and apply the division lemma to get
98 = 34 x 2 + 30
We consider the new divisor 34 and the new remainder 30,and apply the division lemma to get
34 = 30 x 1 + 4
We consider the new divisor 30 and the new remainder 4,and apply the division lemma to get
30 = 4 x 7 + 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 494 and 626 is 2
Notice that 2 = HCF(4,2) = HCF(30,4) = HCF(34,30) = HCF(98,34) = HCF(132,98) = HCF(494,132) = HCF(626,494) .
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 494, 626?
Answer: HCF of 494, 626 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 494, 626 using Euclid's Algorithm?
Answer: For arbitrary numbers 494, 626 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
