HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 786, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 786, 949 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 786, 949 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 786, 949 is 1.
HCF(786, 949) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 786, 949 is 1.
Step 1: Since 949 > 786, we apply the division lemma to 949 and 786, to get
949 = 786 x 1 + 163
Step 2: Since the reminder 786 ≠ 0, we apply division lemma to 163 and 786, to get
786 = 163 x 4 + 134
Step 3: We consider the new divisor 163 and the new remainder 134, and apply the division lemma to get
163 = 134 x 1 + 29
We consider the new divisor 134 and the new remainder 29,and apply the division lemma to get
134 = 29 x 4 + 18
We consider the new divisor 29 and the new remainder 18,and apply the division lemma to get
29 = 18 x 1 + 11
We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get
18 = 11 x 1 + 7
We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 786 and 949 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(29,18) = HCF(134,29) = HCF(163,134) = HCF(786,163) = HCF(949,786) .
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 786, 949?
Answer: HCF of 786, 949 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 786, 949 using Euclid's Algorithm?
Answer: For arbitrary numbers 786, 949 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
