HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 540, 774, 801 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 540, 774, 801 is 9 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 540, 774, 801 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 540, 774, 801 is 9.
HCF(540, 774, 801) = 9
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 540, 774, 801 is 9.
Step 1: Since 774 > 540, we apply the division lemma to 774 and 540, to get
774 = 540 x 1 + 234
Step 2: Since the reminder 540 ≠ 0, we apply division lemma to 234 and 540, to get
540 = 234 x 2 + 72
Step 3: We consider the new divisor 234 and the new remainder 72, and apply the division lemma to get
234 = 72 x 3 + 18
We consider the new divisor 72 and the new remainder 18, and apply the division lemma to get
72 = 18 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 540 and 774 is 18
Notice that 18 = HCF(72,18) = HCF(234,72) = HCF(540,234) = HCF(774,540) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 801 > 18, we apply the division lemma to 801 and 18, to get
801 = 18 x 44 + 9
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 9 and 18, to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 18 and 801 is 9
Notice that 9 = HCF(18,9) = HCF(801,18) .
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 540, 774, 801?
Answer: HCF of 540, 774, 801 is 9 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 540, 774, 801 using Euclid's Algorithm?
Answer: For arbitrary numbers 540, 774, 801 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
