HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 753, 306, 561 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 399, 753, 306, 561 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 399, 753, 306, 561 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 399, 753, 306, 561 is 3.
HCF(399, 753, 306, 561) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 399, 753, 306, 561 is 3.
Step 1: Since 753 > 399, we apply the division lemma to 753 and 399, to get
753 = 399 x 1 + 354
Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 354 and 399, to get
399 = 354 x 1 + 45
Step 3: We consider the new divisor 354 and the new remainder 45, and apply the division lemma to get
354 = 45 x 7 + 39
We consider the new divisor 45 and the new remainder 39,and apply the division lemma to get
45 = 39 x 1 + 6
We consider the new divisor 39 and the new remainder 6,and apply the division lemma to get
39 = 6 x 6 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 399 and 753 is 3
Notice that 3 = HCF(6,3) = HCF(39,6) = HCF(45,39) = HCF(354,45) = HCF(399,354) = HCF(753,399) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 306 > 3, we apply the division lemma to 306 and 3, to get
306 = 3 x 102 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 306 is 3
Notice that 3 = HCF(306,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 561 > 3, we apply the division lemma to 561 and 3, to get
561 = 3 x 187 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 561 is 3
Notice that 3 = HCF(561,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 399, 753, 306, 561?
Answer: HCF of 399, 753, 306, 561 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 399, 753, 306, 561 using Euclid's Algorithm?
Answer: For arbitrary numbers 399, 753, 306, 561 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
