HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 139, 394, 571 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 139, 394, 571 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 139, 394, 571 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 139, 394, 571 is 1.
HCF(139, 394, 571) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 139, 394, 571 is 1.
Step 1: Since 394 > 139, we apply the division lemma to 394 and 139, to get
394 = 139 x 2 + 116
Step 2: Since the reminder 139 ≠ 0, we apply division lemma to 116 and 139, to get
139 = 116 x 1 + 23
Step 3: We consider the new divisor 116 and the new remainder 23, and apply the division lemma to get
116 = 23 x 5 + 1
We consider the new divisor 23 and the new remainder 1, and apply the division lemma to get
23 = 1 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 139 and 394 is 1
Notice that 1 = HCF(23,1) = HCF(116,23) = HCF(139,116) = HCF(394,139) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 571 > 1, we apply the division lemma to 571 and 1, to get
571 = 1 x 571 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 571 is 1
Notice that 1 = HCF(571,1) .
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 139, 394, 571?
Answer: HCF of 139, 394, 571 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 139, 394, 571 using Euclid's Algorithm?
Answer: For arbitrary numbers 139, 394, 571 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
