HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7658, 497 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 7658, 497 is 7 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 7658, 497 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 7658, 497 is 7.
HCF(7658, 497) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7658, 497 is 7.
Step 1: Since 7658 > 497, we apply the division lemma to 7658 and 497, to get
7658 = 497 x 15 + 203
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 203 and 497, to get
497 = 203 x 2 + 91
Step 3: We consider the new divisor 203 and the new remainder 91, and apply the division lemma to get
203 = 91 x 2 + 21
We consider the new divisor 91 and the new remainder 21,and apply the division lemma to get
91 = 21 x 4 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7658 and 497 is 7
Notice that 7 = HCF(21,7) = HCF(91,21) = HCF(203,91) = HCF(497,203) = HCF(7658,497) .
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 7658, 497?
Answer: HCF of 7658, 497 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 7658, 497 using Euclid's Algorithm?
Answer: For arbitrary numbers 7658, 497 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
