HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 780, 346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 780, 346 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 909, 780, 346 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 909, 780, 346 is 1.
HCF(909, 780, 346) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 909, 780, 346 is 1.
Step 1: Since 909 > 780, we apply the division lemma to 909 and 780, to get
909 = 780 x 1 + 129
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 129 and 780, to get
780 = 129 x 6 + 6
Step 3: We consider the new divisor 129 and the new remainder 6, and apply the division lemma to get
129 = 6 x 21 + 3
We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 909 and 780 is 3
Notice that 3 = HCF(6,3) = HCF(129,6) = HCF(780,129) = HCF(909,780) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 346 > 3, we apply the division lemma to 346 and 3, to get
346 = 3 x 115 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 346 is 1
Notice that 1 = HCF(3,1) = HCF(346,3) .
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 909, 780, 346?
Answer: HCF of 909, 780, 346 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 909, 780, 346 using Euclid's Algorithm?
Answer: For arbitrary numbers 909, 780, 346 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
