HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 652, 409 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 652, 409 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 652, 409 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 652, 409 is 1.
HCF(652, 409) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 652, 409 is 1.
Step 1: Since 652 > 409, we apply the division lemma to 652 and 409, to get
652 = 409 x 1 + 243
Step 2: Since the reminder 409 ≠ 0, we apply division lemma to 243 and 409, to get
409 = 243 x 1 + 166
Step 3: We consider the new divisor 243 and the new remainder 166, and apply the division lemma to get
243 = 166 x 1 + 77
We consider the new divisor 166 and the new remainder 77,and apply the division lemma to get
166 = 77 x 2 + 12
We consider the new divisor 77 and the new remainder 12,and apply the division lemma to get
77 = 12 x 6 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 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 652 and 409 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(166,77) = HCF(243,166) = HCF(409,243) = HCF(652,409) .
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 652, 409?
Answer: HCF of 652, 409 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 652, 409 using Euclid's Algorithm?
Answer: For arbitrary numbers 652, 409 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
