HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 902, 228, 578 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 902, 228, 578 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 902, 228, 578 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 902, 228, 578 is 2.
HCF(902, 228, 578) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 902, 228, 578 is 2.
Step 1: Since 902 > 228, we apply the division lemma to 902 and 228, to get
902 = 228 x 3 + 218
Step 2: Since the reminder 228 ≠ 0, we apply division lemma to 218 and 228, to get
228 = 218 x 1 + 10
Step 3: We consider the new divisor 218 and the new remainder 10, and apply the division lemma to get
218 = 10 x 21 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 902 and 228 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(218,10) = HCF(228,218) = HCF(902,228) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 578 > 2, we apply the division lemma to 578 and 2, to get
578 = 2 x 289 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 578 is 2
Notice that 2 = HCF(578,2) .
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 902, 228, 578?
Answer: HCF of 902, 228, 578 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 902, 228, 578 using Euclid's Algorithm?
Answer: For arbitrary numbers 902, 228, 578 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
