HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 624, 398, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 624, 398, 447 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 605, 624, 398, 447 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 605, 624, 398, 447 is 1.
HCF(605, 624, 398, 447) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 624, 398, 447 is 1.
Step 1: Since 624 > 605, we apply the division lemma to 624 and 605, to get
624 = 605 x 1 + 19
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 19 and 605, to get
605 = 19 x 31 + 16
Step 3: We consider the new divisor 19 and the new remainder 16, and apply the division lemma to get
19 = 16 x 1 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 605 and 624 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(605,19) = HCF(624,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 398 > 1, we apply the division lemma to 398 and 1, to get
398 = 1 x 398 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 398 is 1
Notice that 1 = HCF(398,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 447 > 1, we apply the division lemma to 447 and 1, to get
447 = 1 x 447 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 447 is 1
Notice that 1 = HCF(447,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 605, 624, 398, 447?
Answer: HCF of 605, 624, 398, 447 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 605, 624, 398, 447 using Euclid's Algorithm?
Answer: For arbitrary numbers 605, 624, 398, 447 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
