HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 714, 6930, 4539 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 714, 6930, 4539 is 3 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 714, 6930, 4539 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 714, 6930, 4539 is 3.
HCF(714, 6930, 4539) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 714, 6930, 4539 is 3.
Step 1: Since 6930 > 714, we apply the division lemma to 6930 and 714, to get
6930 = 714 x 9 + 504
Step 2: Since the reminder 714 ≠ 0, we apply division lemma to 504 and 714, to get
714 = 504 x 1 + 210
Step 3: We consider the new divisor 504 and the new remainder 210, and apply the division lemma to get
504 = 210 x 2 + 84
We consider the new divisor 210 and the new remainder 84,and apply the division lemma to get
210 = 84 x 2 + 42
We consider the new divisor 84 and the new remainder 42,and apply the division lemma to get
84 = 42 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 42, the HCF of 714 and 6930 is 42
Notice that 42 = HCF(84,42) = HCF(210,84) = HCF(504,210) = HCF(714,504) = HCF(6930,714) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4539 > 42, we apply the division lemma to 4539 and 42, to get
4539 = 42 x 108 + 3
Step 2: Since the reminder 42 ≠ 0, we apply division lemma to 3 and 42, to get
42 = 3 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 42 and 4539 is 3
Notice that 3 = HCF(42,3) = HCF(4539,42) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 714, 6930, 4539?
Answer: HCF of 714, 6930, 4539 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 714, 6930, 4539 using Euclid's Algorithm?
Answer: For arbitrary numbers 714, 6930, 4539 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
