HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 827, 420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 827, 420 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 827, 420 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 827, 420 is 1.
HCF(827, 420) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 827, 420 is 1.
Step 1: Since 827 > 420, we apply the division lemma to 827 and 420, to get
827 = 420 x 1 + 407
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 407 and 420, to get
420 = 407 x 1 + 13
Step 3: We consider the new divisor 407 and the new remainder 13, and apply the division lemma to get
407 = 13 x 31 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 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 827 and 420 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(407,13) = HCF(420,407) = HCF(827,420) .
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 827, 420?
Answer: HCF of 827, 420 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 827, 420 using Euclid's Algorithm?
Answer: For arbitrary numbers 827, 420 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
