HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 769, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 769, 203 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 291, 769, 203 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 291, 769, 203 is 1.
HCF(291, 769, 203) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 769, 203 is 1.
Step 1: Since 769 > 291, we apply the division lemma to 769 and 291, to get
769 = 291 x 2 + 187
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 187 and 291, to get
291 = 187 x 1 + 104
Step 3: We consider the new divisor 187 and the new remainder 104, and apply the division lemma to get
187 = 104 x 1 + 83
We consider the new divisor 104 and the new remainder 83,and apply the division lemma to get
104 = 83 x 1 + 21
We consider the new divisor 83 and the new remainder 21,and apply the division lemma to get
83 = 21 x 3 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 291 and 769 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(83,21) = HCF(104,83) = HCF(187,104) = HCF(291,187) = HCF(769,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get
203 = 1 x 203 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1
Notice that 1 = HCF(203,1) .
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 291, 769, 203?
Answer: HCF of 291, 769, 203 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 291, 769, 203 using Euclid's Algorithm?
Answer: For arbitrary numbers 291, 769, 203 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
