HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 392, 859 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 378, 392, 859 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 378, 392, 859 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 378, 392, 859 is 1.
HCF(378, 392, 859) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 378, 392, 859 is 1.
Step 1: Since 392 > 378, we apply the division lemma to 392 and 378, to get
392 = 378 x 1 + 14
Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 14 and 378, to get
378 = 14 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 378 and 392 is 14
Notice that 14 = HCF(378,14) = HCF(392,378) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 859 > 14, we apply the division lemma to 859 and 14, to get
859 = 14 x 61 + 5
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 5 and 14, to get
14 = 5 x 2 + 4
Step 3: We consider the new divisor 5 and the new remainder 4, and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 14 and 859 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(859,14) .
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 378, 392, 859?
Answer: HCF of 378, 392, 859 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 378, 392, 859 using Euclid's Algorithm?
Answer: For arbitrary numbers 378, 392, 859 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
