HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 211 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 211 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 784, 211 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 784, 211 is 1.
HCF(784, 211) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 211 is 1.
Step 1: Since 784 > 211, we apply the division lemma to 784 and 211, to get
784 = 211 x 3 + 151
Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 151 and 211, to get
211 = 151 x 1 + 60
Step 3: We consider the new divisor 151 and the new remainder 60, and apply the division lemma to get
151 = 60 x 2 + 31
We consider the new divisor 60 and the new remainder 31,and apply the division lemma to get
60 = 31 x 1 + 29
We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get
31 = 29 x 1 + 2
We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get
29 = 2 x 14 + 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 784 and 211 is 1
Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(60,31) = HCF(151,60) = HCF(211,151) = HCF(784,211) .
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 784, 211?
Answer: HCF of 784, 211 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 784, 211 using Euclid's Algorithm?
Answer: For arbitrary numbers 784, 211 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
