HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 348, 555, 330, 561 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 348, 555, 330, 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 348, 555, 330, 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 348, 555, 330, 561 is 3.
HCF(348, 555, 330, 561) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 348, 555, 330, 561 is 3.
Step 1: Since 555 > 348, we apply the division lemma to 555 and 348, to get
555 = 348 x 1 + 207
Step 2: Since the reminder 348 ≠ 0, we apply division lemma to 207 and 348, to get
348 = 207 x 1 + 141
Step 3: We consider the new divisor 207 and the new remainder 141, and apply the division lemma to get
207 = 141 x 1 + 66
We consider the new divisor 141 and the new remainder 66,and apply the division lemma to get
141 = 66 x 2 + 9
We consider the new divisor 66 and the new remainder 9,and apply the division lemma to get
66 = 9 x 7 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 348 and 555 is 3
Notice that 3 = HCF(9,3) = HCF(66,9) = HCF(141,66) = HCF(207,141) = HCF(348,207) = HCF(555,348) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 330 > 3, we apply the division lemma to 330 and 3, to get
330 = 3 x 110 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 330 is 3
Notice that 3 = HCF(330,3) .
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 348, 555, 330, 561?
Answer: HCF of 348, 555, 330, 561 is 3 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 348, 555, 330, 561 using Euclid's Algorithm?
Answer: For arbitrary numbers 348, 555, 330, 561 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
