HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 510, 621 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 510, 621 is 3 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 510, 621 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 510, 621 is 3.
HCF(510, 621) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 510, 621 is 3.
Step 1: Since 621 > 510, we apply the division lemma to 621 and 510, to get
621 = 510 x 1 + 111
Step 2: Since the reminder 510 ≠ 0, we apply division lemma to 111 and 510, to get
510 = 111 x 4 + 66
Step 3: We consider the new divisor 111 and the new remainder 66, and apply the division lemma to get
111 = 66 x 1 + 45
We consider the new divisor 66 and the new remainder 45,and apply the division lemma to get
66 = 45 x 1 + 21
We consider the new divisor 45 and the new remainder 21,and apply the division lemma to get
45 = 21 x 2 + 3
We consider the new divisor 21 and the new remainder 3,and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 510 and 621 is 3
Notice that 3 = HCF(21,3) = HCF(45,21) = HCF(66,45) = HCF(111,66) = HCF(510,111) = HCF(621,510) .
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 510, 621?
Answer: HCF of 510, 621 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 510, 621 using Euclid's Algorithm?
Answer: For arbitrary numbers 510, 621 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
