HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 254, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 254, 641 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 254, 641 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 254, 641 is 1.
HCF(254, 641) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 254, 641 is 1.
Step 1: Since 641 > 254, we apply the division lemma to 641 and 254, to get
641 = 254 x 2 + 133
Step 2: Since the reminder 254 ≠ 0, we apply division lemma to 133 and 254, to get
254 = 133 x 1 + 121
Step 3: We consider the new divisor 133 and the new remainder 121, and apply the division lemma to get
133 = 121 x 1 + 12
We consider the new divisor 121 and the new remainder 12,and apply the division lemma to get
121 = 12 x 10 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 254 and 641 is 1
Notice that 1 = HCF(12,1) = HCF(121,12) = HCF(133,121) = HCF(254,133) = HCF(641,254) .
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 254, 641?
Answer: HCF of 254, 641 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 254, 641 using Euclid's Algorithm?
Answer: For arbitrary numbers 254, 641 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
