HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 205 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 205 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 354, 205 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 354, 205 is 1.
HCF(354, 205) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 354, 205 is 1.
Step 1: Since 354 > 205, we apply the division lemma to 354 and 205, to get
354 = 205 x 1 + 149
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 149 and 205, to get
205 = 149 x 1 + 56
Step 3: We consider the new divisor 149 and the new remainder 56, and apply the division lemma to get
149 = 56 x 2 + 37
We consider the new divisor 56 and the new remainder 37,and apply the division lemma to get
56 = 37 x 1 + 19
We consider the new divisor 37 and the new remainder 19,and apply the division lemma to get
37 = 19 x 1 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 354 and 205 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(37,19) = HCF(56,37) = HCF(149,56) = HCF(205,149) = HCF(354,205) .
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 354, 205?
Answer: HCF of 354, 205 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 354, 205 using Euclid's Algorithm?
Answer: For arbitrary numbers 354, 205 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
