HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 790, 511, 706 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 790, 511, 706 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 790, 511, 706 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 790, 511, 706 is 1.
HCF(790, 511, 706) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 790, 511, 706 is 1.
Step 1: Since 790 > 511, we apply the division lemma to 790 and 511, to get
790 = 511 x 1 + 279
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 279 and 511, to get
511 = 279 x 1 + 232
Step 3: We consider the new divisor 279 and the new remainder 232, and apply the division lemma to get
279 = 232 x 1 + 47
We consider the new divisor 232 and the new remainder 47,and apply the division lemma to get
232 = 47 x 4 + 44
We consider the new divisor 47 and the new remainder 44,and apply the division lemma to get
47 = 44 x 1 + 3
We consider the new divisor 44 and the new remainder 3,and apply the division lemma to get
44 = 3 x 14 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 790 and 511 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(44,3) = HCF(47,44) = HCF(232,47) = HCF(279,232) = HCF(511,279) = HCF(790,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 1, we apply the division lemma to 706 and 1, to get
706 = 1 x 706 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 706 is 1
Notice that 1 = HCF(706,1) .
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 790, 511, 706?
Answer: HCF of 790, 511, 706 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 790, 511, 706 using Euclid's Algorithm?
Answer: For arbitrary numbers 790, 511, 706 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
