HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 724, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 724, 406 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 869, 724, 406 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 869, 724, 406 is 1.
HCF(869, 724, 406) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 724, 406 is 1.
Step 1: Since 869 > 724, we apply the division lemma to 869 and 724, to get
869 = 724 x 1 + 145
Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 145 and 724, to get
724 = 145 x 4 + 144
Step 3: We consider the new divisor 145 and the new remainder 144, and apply the division lemma to get
145 = 144 x 1 + 1
We consider the new divisor 144 and the new remainder 1, and apply the division lemma to get
144 = 1 x 144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 724 is 1
Notice that 1 = HCF(144,1) = HCF(145,144) = HCF(724,145) = HCF(869,724) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get
406 = 1 x 406 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1
Notice that 1 = HCF(406,1) .
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 869, 724, 406?
Answer: HCF of 869, 724, 406 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 869, 724, 406 using Euclid's Algorithm?
Answer: For arbitrary numbers 869, 724, 406 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
