HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 263, 414, 557, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 263, 414, 557, 455 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 263, 414, 557, 455 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 263, 414, 557, 455 is 1.
HCF(263, 414, 557, 455) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 263, 414, 557, 455 is 1.
Step 1: Since 414 > 263, we apply the division lemma to 414 and 263, to get
414 = 263 x 1 + 151
Step 2: Since the reminder 263 ≠ 0, we apply division lemma to 151 and 263, to get
263 = 151 x 1 + 112
Step 3: We consider the new divisor 151 and the new remainder 112, and apply the division lemma to get
151 = 112 x 1 + 39
We consider the new divisor 112 and the new remainder 39,and apply the division lemma to get
112 = 39 x 2 + 34
We consider the new divisor 39 and the new remainder 34,and apply the division lemma to get
39 = 34 x 1 + 5
We consider the new divisor 34 and the new remainder 5,and apply the division lemma to get
34 = 5 x 6 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 263 and 414 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(34,5) = HCF(39,34) = HCF(112,39) = HCF(151,112) = HCF(263,151) = HCF(414,263) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 557 > 1, we apply the division lemma to 557 and 1, to get
557 = 1 x 557 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 557 is 1
Notice that 1 = HCF(557,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 455 > 1, we apply the division lemma to 455 and 1, to get
455 = 1 x 455 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 455 is 1
Notice that 1 = HCF(455,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

3. How to find HCF of 263, 414, 557, 455 using Euclid's Algorithm?
Answer: For arbitrary numbers 263, 414, 557, 455 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
