HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 826, 847 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 826, 847 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 651, 826, 847 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 651, 826, 847 is 7.
HCF(651, 826, 847) = 7
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 826, 847 is 7.
Step 1: Since 826 > 651, we apply the division lemma to 826 and 651, to get
826 = 651 x 1 + 175
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 175 and 651, to get
651 = 175 x 3 + 126
Step 3: We consider the new divisor 175 and the new remainder 126, and apply the division lemma to get
175 = 126 x 1 + 49
We consider the new divisor 126 and the new remainder 49,and apply the division lemma to get
126 = 49 x 2 + 28
We consider the new divisor 49 and the new remainder 28,and apply the division lemma to get
49 = 28 x 1 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 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 651 and 826 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(49,28) = HCF(126,49) = HCF(175,126) = HCF(651,175) = HCF(826,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 847 > 7, we apply the division lemma to 847 and 7, to get
847 = 7 x 121 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 847 is 7
Notice that 7 = HCF(847,7) .
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 651, 826, 847?
Answer: HCF of 651, 826, 847 is 7 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 651, 826, 847 using Euclid's Algorithm?
Answer: For arbitrary numbers 651, 826, 847 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
