HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 759, 616, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 759, 616, 395 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 759, 616, 395 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 759, 616, 395 is 1.
HCF(759, 616, 395) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 759, 616, 395 is 1.
Step 1: Since 759 > 616, we apply the division lemma to 759 and 616, to get
759 = 616 x 1 + 143
Step 2: Since the reminder 616 ≠ 0, we apply division lemma to 143 and 616, to get
616 = 143 x 4 + 44
Step 3: We consider the new divisor 143 and the new remainder 44, and apply the division lemma to get
143 = 44 x 3 + 11
We consider the new divisor 44 and the new remainder 11, and apply the division lemma to get
44 = 11 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 759 and 616 is 11
Notice that 11 = HCF(44,11) = HCF(143,44) = HCF(616,143) = HCF(759,616) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 11, we apply the division lemma to 395 and 11, to get
395 = 11 x 35 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 395 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(395,11) .
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 759, 616, 395?
Answer: HCF of 759, 616, 395 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 759, 616, 395 using Euclid's Algorithm?
Answer: For arbitrary numbers 759, 616, 395 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
