HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 758, 668, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 758, 668, 651 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, 668, 651 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, 668, 651 is 1.
HCF(758, 668, 651) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 758, 668, 651 is 1.
Step 1: Since 758 > 668, we apply the division lemma to 758 and 668, to get
758 = 668 x 1 + 90
Step 2: Since the reminder 668 ≠ 0, we apply division lemma to 90 and 668, to get
668 = 90 x 7 + 38
Step 3: We consider the new divisor 90 and the new remainder 38, and apply the division lemma to get
90 = 38 x 2 + 14
We consider the new divisor 38 and the new remainder 14,and apply the division lemma to get
38 = 14 x 2 + 10
We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 758 and 668 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(38,14) = HCF(90,38) = HCF(668,90) = HCF(758,668) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 2, we apply the division lemma to 651 and 2, to get
651 = 2 x 325 + 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 651 is 1
Notice that 1 = HCF(2,1) = HCF(651,2) .
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, 668, 651?
Answer: HCF of 758, 668, 651 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 758, 668, 651 using Euclid's Algorithm?
Answer: For arbitrary numbers 758, 668, 651 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
