HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 700, 905, 675 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 700, 905, 675 is 5 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 700, 905, 675 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 700, 905, 675 is 5.
HCF(700, 905, 675) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 700, 905, 675 is 5.
Step 1: Since 905 > 700, we apply the division lemma to 905 and 700, to get
905 = 700 x 1 + 205
Step 2: Since the reminder 700 ≠ 0, we apply division lemma to 205 and 700, to get
700 = 205 x 3 + 85
Step 3: We consider the new divisor 205 and the new remainder 85, and apply the division lemma to get
205 = 85 x 2 + 35
We consider the new divisor 85 and the new remainder 35,and apply the division lemma to get
85 = 35 x 2 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 700 and 905 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(85,35) = HCF(205,85) = HCF(700,205) = HCF(905,700) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 5, we apply the division lemma to 675 and 5, to get
675 = 5 x 135 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 675 is 5
Notice that 5 = HCF(675,5) .
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 700, 905, 675?
Answer: HCF of 700, 905, 675 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 700, 905, 675 using Euclid's Algorithm?
Answer: For arbitrary numbers 700, 905, 675 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
