HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 641, 359, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 641, 359, 663 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 641, 359, 663 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 641, 359, 663 is 1.
HCF(641, 359, 663) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 641, 359, 663 is 1.
Step 1: Since 641 > 359, we apply the division lemma to 641 and 359, to get
641 = 359 x 1 + 282
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 282 and 359, to get
359 = 282 x 1 + 77
Step 3: We consider the new divisor 282 and the new remainder 77, and apply the division lemma to get
282 = 77 x 3 + 51
We consider the new divisor 77 and the new remainder 51,and apply the division lemma to get
77 = 51 x 1 + 26
We consider the new divisor 51 and the new remainder 26,and apply the division lemma to get
51 = 26 x 1 + 25
We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get
26 = 25 x 1 + 1
We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 641 and 359 is 1
Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(51,26) = HCF(77,51) = HCF(282,77) = HCF(359,282) = HCF(641,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 663 > 1, we apply the division lemma to 663 and 1, to get
663 = 1 x 663 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 663 is 1
Notice that 1 = HCF(663,1) .
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 641, 359, 663?
Answer: HCF of 641, 359, 663 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 641, 359, 663 using Euclid's Algorithm?
Answer: For arbitrary numbers 641, 359, 663 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
