HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 312, 999, 404, 603 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 312, 999, 404, 603 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 312, 999, 404, 603 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 312, 999, 404, 603 is 1.
HCF(312, 999, 404, 603) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 312, 999, 404, 603 is 1.
Step 1: Since 999 > 312, we apply the division lemma to 999 and 312, to get
999 = 312 x 3 + 63
Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 63 and 312, to get
312 = 63 x 4 + 60
Step 3: We consider the new divisor 63 and the new remainder 60, and apply the division lemma to get
63 = 60 x 1 + 3
We consider the new divisor 60 and the new remainder 3, and apply the division lemma to get
60 = 3 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 312 and 999 is 3
Notice that 3 = HCF(60,3) = HCF(63,60) = HCF(312,63) = HCF(999,312) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 404 > 3, we apply the division lemma to 404 and 3, to get
404 = 3 x 134 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 404 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(404,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 603 > 1, we apply the division lemma to 603 and 1, to get
603 = 1 x 603 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 603 is 1
Notice that 1 = HCF(603,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 312, 999, 404, 603?
Answer: HCF of 312, 999, 404, 603 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 312, 999, 404, 603 using Euclid's Algorithm?
