HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 659, 702, 471 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 659, 702, 471 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 659, 702, 471 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 659, 702, 471 is 1.
HCF(659, 702, 471) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 659, 702, 471 is 1.
Step 1: Since 702 > 659, we apply the division lemma to 702 and 659, to get
702 = 659 x 1 + 43
Step 2: Since the reminder 659 ≠ 0, we apply division lemma to 43 and 659, to get
659 = 43 x 15 + 14
Step 3: We consider the new divisor 43 and the new remainder 14, and apply the division lemma to get
43 = 14 x 3 + 1
We consider the new divisor 14 and the new remainder 1, and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 659 and 702 is 1
Notice that 1 = HCF(14,1) = HCF(43,14) = HCF(659,43) = HCF(702,659) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 471 > 1, we apply the division lemma to 471 and 1, to get
471 = 1 x 471 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 471 is 1
Notice that 1 = HCF(471,1) .
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 659, 702, 471?
Answer: HCF of 659, 702, 471 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 659, 702, 471 using Euclid's Algorithm?
Answer: For arbitrary numbers 659, 702, 471 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
