HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 435, 668, 540 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 435, 668, 540 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 435, 668, 540 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 435, 668, 540 is 1.
HCF(435, 668, 540) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 435, 668, 540 is 1.
Step 1: Since 668 > 435, we apply the division lemma to 668 and 435, to get
668 = 435 x 1 + 233
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 233 and 435, to get
435 = 233 x 1 + 202
Step 3: We consider the new divisor 233 and the new remainder 202, and apply the division lemma to get
233 = 202 x 1 + 31
We consider the new divisor 202 and the new remainder 31,and apply the division lemma to get
202 = 31 x 6 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 435 and 668 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(202,31) = HCF(233,202) = HCF(435,233) = HCF(668,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 540 > 1, we apply the division lemma to 540 and 1, to get
540 = 1 x 540 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 540 is 1
Notice that 1 = HCF(540,1) .
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 435, 668, 540?
Answer: HCF of 435, 668, 540 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 435, 668, 540 using Euclid's Algorithm?
Answer: For arbitrary numbers 435, 668, 540 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
