HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 28, 856 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 28, 856 is 2 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 170, 28, 856 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 170, 28, 856 is 2.
HCF(170, 28, 856) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 170, 28, 856 is 2.
Step 1: Since 170 > 28, we apply the division lemma to 170 and 28, to get
170 = 28 x 6 + 2
Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 2 and 28, to get
28 = 2 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 170 and 28 is 2
Notice that 2 = HCF(28,2) = HCF(170,28) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 2, we apply the division lemma to 856 and 2, to get
856 = 2 x 428 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 856 is 2
Notice that 2 = HCF(856,2) .
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 170, 28, 856?
Answer: HCF of 170, 28, 856 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 170, 28, 856 using Euclid's Algorithm?
Answer: For arbitrary numbers 170, 28, 856 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
