HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 854, 255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 854, 255 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 854, 255 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 854, 255 is 1.
HCF(854, 255) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 854, 255 is 1.
Step 1: Since 854 > 255, we apply the division lemma to 854 and 255, to get
854 = 255 x 3 + 89
Step 2: Since the reminder 255 ≠ 0, we apply division lemma to 89 and 255, to get
255 = 89 x 2 + 77
Step 3: We consider the new divisor 89 and the new remainder 77, and apply the division lemma to get
89 = 77 x 1 + 12
We consider the new divisor 77 and the new remainder 12,and apply the division lemma to get
77 = 12 x 6 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 854 and 255 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(89,77) = HCF(255,89) = HCF(854,255) .
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 854, 255?
Answer: HCF of 854, 255 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 854, 255 using Euclid's Algorithm?
Answer: For arbitrary numbers 854, 255 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
