HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 436, 685, 910 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 436, 685, 910 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 436, 685, 910 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 436, 685, 910 is 1.
HCF(436, 685, 910) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 436, 685, 910 is 1.
Step 1: Since 685 > 436, we apply the division lemma to 685 and 436, to get
685 = 436 x 1 + 249
Step 2: Since the reminder 436 ≠ 0, we apply division lemma to 249 and 436, to get
436 = 249 x 1 + 187
Step 3: We consider the new divisor 249 and the new remainder 187, and apply the division lemma to get
249 = 187 x 1 + 62
We consider the new divisor 187 and the new remainder 62,and apply the division lemma to get
187 = 62 x 3 + 1
We consider the new divisor 62 and the new remainder 1,and apply the division lemma to get
62 = 1 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 436 and 685 is 1
Notice that 1 = HCF(62,1) = HCF(187,62) = HCF(249,187) = HCF(436,249) = HCF(685,436) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 910 > 1, we apply the division lemma to 910 and 1, to get
910 = 1 x 910 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 910 is 1
Notice that 1 = HCF(910,1) .
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 436, 685, 910?
Answer: HCF of 436, 685, 910 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 436, 685, 910 using Euclid's Algorithm?
Answer: For arbitrary numbers 436, 685, 910 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
