HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 658, 657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 658, 657 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 658, 657 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 658, 657 is 1.
HCF(658, 657) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 658, 657 is 1.
Step 1: Since 658 > 657, we apply the division lemma to 658 and 657, to get
658 = 657 x 1 + 1
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 1 and 657, to get
657 = 1 x 657 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 658 and 657 is 1
Notice that 1 = HCF(657,1) = HCF(658,657) .
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 658, 657?
Answer: HCF of 658, 657 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 658, 657 using Euclid's Algorithm?
Answer: For arbitrary numbers 658, 657 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
