HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 727, 217 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 727, 217 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 278, 727, 217 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 278, 727, 217 is 1.
HCF(278, 727, 217) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 278, 727, 217 is 1.
Step 1: Since 727 > 278, we apply the division lemma to 727 and 278, to get
727 = 278 x 2 + 171
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 171 and 278, to get
278 = 171 x 1 + 107
Step 3: We consider the new divisor 171 and the new remainder 107, and apply the division lemma to get
171 = 107 x 1 + 64
We consider the new divisor 107 and the new remainder 64,and apply the division lemma to get
107 = 64 x 1 + 43
We consider the new divisor 64 and the new remainder 43,and apply the division lemma to get
64 = 43 x 1 + 21
We consider the new divisor 43 and the new remainder 21,and apply the division lemma to get
43 = 21 x 2 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 278 and 727 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(64,43) = HCF(107,64) = HCF(171,107) = HCF(278,171) = HCF(727,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 217 > 1, we apply the division lemma to 217 and 1, to get
217 = 1 x 217 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 217 is 1
Notice that 1 = HCF(217,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 278, 727, 217?
Answer: HCF of 278, 727, 217 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 278, 727, 217 using Euclid's Algorithm?
Answer: For arbitrary numbers 278, 727, 217 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
