HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 442, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 442, 641 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 442, 641 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 442, 641 is 1.
HCF(442, 641) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 442, 641 is 1.
Step 1: Since 641 > 442, we apply the division lemma to 641 and 442, to get
641 = 442 x 1 + 199
Step 2: Since the reminder 442 ≠ 0, we apply division lemma to 199 and 442, to get
442 = 199 x 2 + 44
Step 3: We consider the new divisor 199 and the new remainder 44, and apply the division lemma to get
199 = 44 x 4 + 23
We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get
44 = 23 x 1 + 21
We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 442 and 641 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(199,44) = HCF(442,199) = HCF(641,442) .
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 442, 641?
Answer: HCF of 442, 641 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 442, 641 using Euclid's Algorithm?
Answer: For arbitrary numbers 442, 641 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
