HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6404, 1255 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6404, 1255 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 6404, 1255 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 6404, 1255 is 1.
HCF(6404, 1255) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6404, 1255 is 1.
Step 1: Since 6404 > 1255, we apply the division lemma to 6404 and 1255, to get
6404 = 1255 x 5 + 129
Step 2: Since the reminder 1255 ≠ 0, we apply division lemma to 129 and 1255, to get
1255 = 129 x 9 + 94
Step 3: We consider the new divisor 129 and the new remainder 94, and apply the division lemma to get
129 = 94 x 1 + 35
We consider the new divisor 94 and the new remainder 35,and apply the division lemma to get
94 = 35 x 2 + 24
We consider the new divisor 35 and the new remainder 24,and apply the division lemma to get
35 = 24 x 1 + 11
We consider the new divisor 24 and the new remainder 11,and apply the division lemma to get
24 = 11 x 2 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6404 and 1255 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(24,11) = HCF(35,24) = HCF(94,35) = HCF(129,94) = HCF(1255,129) = HCF(6404,1255) .
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 6404, 1255?
Answer: HCF of 6404, 1255 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 6404, 1255 using Euclid's Algorithm?
Answer: For arbitrary numbers 6404, 1255 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
