HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 974, 256 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 974, 256 is 2 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 284, 974, 256 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 284, 974, 256 is 2.
HCF(284, 974, 256) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 284, 974, 256 is 2.
Step 1: Since 974 > 284, we apply the division lemma to 974 and 284, to get
974 = 284 x 3 + 122
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 122 and 284, to get
284 = 122 x 2 + 40
Step 3: We consider the new divisor 122 and the new remainder 40, and apply the division lemma to get
122 = 40 x 3 + 2
We consider the new divisor 40 and the new remainder 2, and apply the division lemma to get
40 = 2 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 284 and 974 is 2
Notice that 2 = HCF(40,2) = HCF(122,40) = HCF(284,122) = HCF(974,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 256 > 2, we apply the division lemma to 256 and 2, to get
256 = 2 x 128 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 256 is 2
Notice that 2 = HCF(256,2) .
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 284, 974, 256?
Answer: HCF of 284, 974, 256 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 284, 974, 256 using Euclid's Algorithm?
Answer: For arbitrary numbers 284, 974, 256 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
