HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 705, 477 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 705, 477 is 3 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 705, 477 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 705, 477 is 3.
HCF(705, 477) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 705, 477 is 3.
Step 1: Since 705 > 477, we apply the division lemma to 705 and 477, to get
705 = 477 x 1 + 228
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 228 and 477, to get
477 = 228 x 2 + 21
Step 3: We consider the new divisor 228 and the new remainder 21, and apply the division lemma to get
228 = 21 x 10 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 705 and 477 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(228,21) = HCF(477,228) = HCF(705,477) .
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 705, 477?
Answer: HCF of 705, 477 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 705, 477 using Euclid's Algorithm?
Answer: For arbitrary numbers 705, 477 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
