HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 915, 24 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 915, 24 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 428, 915, 24 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 428, 915, 24 is 1.
HCF(428, 915, 24) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 915, 24 is 1.
Step 1: Since 915 > 428, we apply the division lemma to 915 and 428, to get
915 = 428 x 2 + 59
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 59 and 428, to get
428 = 59 x 7 + 15
Step 3: We consider the new divisor 59 and the new remainder 15, and apply the division lemma to get
59 = 15 x 3 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 428 and 915 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(59,15) = HCF(428,59) = HCF(915,428) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1
Notice that 1 = HCF(24,1) .
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 428, 915, 24?
Answer: HCF of 428, 915, 24 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 428, 915, 24 using Euclid's Algorithm?
Answer: For arbitrary numbers 428, 915, 24 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
