HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 867, 352 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 270, 867, 352 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 270, 867, 352 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 270, 867, 352 is 1.
HCF(270, 867, 352) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 270, 867, 352 is 1.
Step 1: Since 867 > 270, we apply the division lemma to 867 and 270, to get
867 = 270 x 3 + 57
Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 57 and 270, to get
270 = 57 x 4 + 42
Step 3: We consider the new divisor 57 and the new remainder 42, and apply the division lemma to get
57 = 42 x 1 + 15
We consider the new divisor 42 and the new remainder 15,and apply the division lemma to get
42 = 15 x 2 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 270 and 867 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(57,42) = HCF(270,57) = HCF(867,270) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 352 > 3, we apply the division lemma to 352 and 3, to get
352 = 3 x 117 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 352 is 1
Notice that 1 = HCF(3,1) = HCF(352,3) .
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 270, 867, 352?
Answer: HCF of 270, 867, 352 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 270, 867, 352 using Euclid's Algorithm?
Answer: For arbitrary numbers 270, 867, 352 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
