HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 822, 539, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 822, 539, 54 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 822, 539, 54 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 822, 539, 54 is 1.
HCF(822, 539, 54) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 822, 539, 54 is 1.
Step 1: Since 822 > 539, we apply the division lemma to 822 and 539, to get
822 = 539 x 1 + 283
Step 2: Since the reminder 539 ≠ 0, we apply division lemma to 283 and 539, to get
539 = 283 x 1 + 256
Step 3: We consider the new divisor 283 and the new remainder 256, and apply the division lemma to get
283 = 256 x 1 + 27
We consider the new divisor 256 and the new remainder 27,and apply the division lemma to get
256 = 27 x 9 + 13
We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get
27 = 13 x 2 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 822 and 539 is 1
Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(256,27) = HCF(283,256) = HCF(539,283) = HCF(822,539) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get
54 = 1 x 54 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1
Notice that 1 = HCF(54,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 822, 539, 54?
Answer: HCF of 822, 539, 54 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 822, 539, 54 using Euclid's Algorithm?
Answer: For arbitrary numbers 822, 539, 54 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
