HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 539, 422, 454 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 539, 422, 454 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 539, 422, 454 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 539, 422, 454 is 1.
HCF(539, 422, 454) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 539, 422, 454 is 1.
Step 1: Since 539 > 422, we apply the division lemma to 539 and 422, to get
539 = 422 x 1 + 117
Step 2: Since the reminder 422 ≠ 0, we apply division lemma to 117 and 422, to get
422 = 117 x 3 + 71
Step 3: We consider the new divisor 117 and the new remainder 71, and apply the division lemma to get
117 = 71 x 1 + 46
We consider the new divisor 71 and the new remainder 46,and apply the division lemma to get
71 = 46 x 1 + 25
We consider the new divisor 46 and the new remainder 25,and apply the division lemma to get
46 = 25 x 1 + 21
We consider the new divisor 25 and the new remainder 21,and apply the division lemma to get
25 = 21 x 1 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 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 539 and 422 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(25,21) = HCF(46,25) = HCF(71,46) = HCF(117,71) = HCF(422,117) = HCF(539,422) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 454 > 1, we apply the division lemma to 454 and 1, to get
454 = 1 x 454 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 454 is 1
Notice that 1 = HCF(454,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 539, 422, 454?
Answer: HCF of 539, 422, 454 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 539, 422, 454 using Euclid's Algorithm?
Answer: For arbitrary numbers 539, 422, 454 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
