HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 630, 643, 614 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 240, 630, 643, 614 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 240, 630, 643, 614 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 240, 630, 643, 614 is 1.
HCF(240, 630, 643, 614) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 240, 630, 643, 614 is 1.
Step 1: Since 630 > 240, we apply the division lemma to 630 and 240, to get
630 = 240 x 2 + 150
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 150 and 240, to get
240 = 150 x 1 + 90
Step 3: We consider the new divisor 150 and the new remainder 90, and apply the division lemma to get
150 = 90 x 1 + 60
We consider the new divisor 90 and the new remainder 60,and apply the division lemma to get
90 = 60 x 1 + 30
We consider the new divisor 60 and the new remainder 30,and apply the division lemma to get
60 = 30 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 240 and 630 is 30
Notice that 30 = HCF(60,30) = HCF(90,60) = HCF(150,90) = HCF(240,150) = HCF(630,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 643 > 30, we apply the division lemma to 643 and 30, to get
643 = 30 x 21 + 13
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 13 and 30, to get
30 = 13 x 2 + 4
Step 3: We consider the new divisor 13 and the new remainder 4, and apply the division lemma to get
13 = 4 x 3 + 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 30 and 643 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(643,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 614 > 1, we apply the division lemma to 614 and 1, to get
614 = 1 x 614 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 614 is 1
Notice that 1 = HCF(614,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 240, 630, 643, 614?
Answer: HCF of 240, 630, 643, 614 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 240, 630, 643, 614 using Euclid's Algorithm?
Answer: For arbitrary numbers 240, 630, 643, 614 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
