HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 290, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 290, 65 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 758, 290, 65 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 758, 290, 65 is 1.
HCF(758, 290, 65) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 758, 290, 65 is 1.
Step 1: Since 758 > 290, we apply the division lemma to 758 and 290, to get
758 = 290 x 2 + 178
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 178 and 290, to get
290 = 178 x 1 + 112
Step 3: We consider the new divisor 178 and the new remainder 112, and apply the division lemma to get
178 = 112 x 1 + 66
We consider the new divisor 112 and the new remainder 66,and apply the division lemma to get
112 = 66 x 1 + 46
We consider the new divisor 66 and the new remainder 46,and apply the division lemma to get
66 = 46 x 1 + 20
We consider the new divisor 46 and the new remainder 20,and apply the division lemma to get
46 = 20 x 2 + 6
We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get
20 = 6 x 3 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 758 and 290 is 2
Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(46,20) = HCF(66,46) = HCF(112,66) = HCF(178,112) = HCF(290,178) = HCF(758,290) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 2, we apply the division lemma to 65 and 2, to get
65 = 2 x 32 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 65 is 1
Notice that 1 = HCF(2,1) = HCF(65,2) .
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 758, 290, 65?
Answer: HCF of 758, 290, 65 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 758, 290, 65 using Euclid's Algorithm?
Answer: For arbitrary numbers 758, 290, 65 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
