HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 766, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 766, 845 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 766, 845 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 766, 845 is 1.
HCF(766, 845) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 766, 845 is 1.
Step 1: Since 845 > 766, we apply the division lemma to 845 and 766, to get
845 = 766 x 1 + 79
Step 2: Since the reminder 766 ≠ 0, we apply division lemma to 79 and 766, to get
766 = 79 x 9 + 55
Step 3: We consider the new divisor 79 and the new remainder 55, and apply the division lemma to get
79 = 55 x 1 + 24
We consider the new divisor 55 and the new remainder 24,and apply the division lemma to get
55 = 24 x 2 + 7
We consider the new divisor 24 and the new remainder 7,and apply the division lemma to get
24 = 7 x 3 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 766 and 845 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(24,7) = HCF(55,24) = HCF(79,55) = HCF(766,79) = HCF(845,766) .
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 766, 845?
Answer: HCF of 766, 845 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 766, 845 using Euclid's Algorithm?
Answer: For arbitrary numbers 766, 845 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
