HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 897, 705 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 897, 705 is 3 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 897, 705 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 897, 705 is 3.
HCF(897, 705) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 897, 705 is 3.
Step 1: Since 897 > 705, we apply the division lemma to 897 and 705, to get
897 = 705 x 1 + 192
Step 2: Since the reminder 705 ≠ 0, we apply division lemma to 192 and 705, to get
705 = 192 x 3 + 129
Step 3: We consider the new divisor 192 and the new remainder 129, and apply the division lemma to get
192 = 129 x 1 + 63
We consider the new divisor 129 and the new remainder 63,and apply the division lemma to get
129 = 63 x 2 + 3
We consider the new divisor 63 and the new remainder 3,and apply the division lemma to get
63 = 3 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 897 and 705 is 3
Notice that 3 = HCF(63,3) = HCF(129,63) = HCF(192,129) = HCF(705,192) = HCF(897,705) .
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 897, 705?
Answer: HCF of 897, 705 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 897, 705 using Euclid's Algorithm?
Answer: For arbitrary numbers 897, 705 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
