HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 43, 87, 65, 446 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 43, 87, 65, 446 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 43, 87, 65, 446 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 43, 87, 65, 446 is 1.
HCF(43, 87, 65, 446) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 43, 87, 65, 446 is 1.
Step 1: Since 87 > 43, we apply the division lemma to 87 and 43, to get
87 = 43 x 2 + 1
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 1 and 43, to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 87 is 1
Notice that 1 = HCF(43,1) = HCF(87,43) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 1, we apply the division lemma to 65 and 1, to get
65 = 1 x 65 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 65 is 1
Notice that 1 = HCF(65,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 446 > 1, we apply the division lemma to 446 and 1, to get
446 = 1 x 446 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 446 is 1
Notice that 1 = HCF(446,1) .
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 43, 87, 65, 446?
Answer: HCF of 43, 87, 65, 446 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 43, 87, 65, 446 using Euclid's Algorithm?
Answer: For arbitrary numbers 43, 87, 65, 446 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
