HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 856 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 495, 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 495, 856 is 1.
HCF(495, 856) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 495, 856 is 1.
Step 1: Since 856 > 495, we apply the division lemma to 856 and 495, to get
856 = 495 x 1 + 361
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 361 and 495, to get
495 = 361 x 1 + 134
Step 3: We consider the new divisor 361 and the new remainder 134, and apply the division lemma to get
361 = 134 x 2 + 93
We consider the new divisor 134 and the new remainder 93,and apply the division lemma to get
134 = 93 x 1 + 41
We consider the new divisor 93 and the new remainder 41,and apply the division lemma to get
93 = 41 x 2 + 11
We consider the new divisor 41 and the new remainder 11,and apply the division lemma to get
41 = 11 x 3 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 495 and 856 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(41,11) = HCF(93,41) = HCF(134,93) = HCF(361,134) = HCF(495,361) = HCF(856,495) .
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 495, 856?
Answer: HCF of 495, 856 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 495, 856 using Euclid's Algorithm?
Answer: For arbitrary numbers 495, 856 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
