HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 603, 7072, 4431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 603, 7072, 4431 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 603, 7072, 4431 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 603, 7072, 4431 is 1.

HCF(603, 7072, 4431) = 1

Highest common factor (HCF) of 603, 7072, 4431 is 1.

Highest Common Factor of 603,7072,4431 using Euclid's algorithm

Highest Common Factor of 603,7072,4431 is 1

Step 1: Since 7072 > 603, we apply the division lemma to 7072 and 603, to get

7072 = 603 x 11 + 439

Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 439 and 603, to get

603 = 439 x 1 + 164

Step 3: We consider the new divisor 439 and the new remainder 164, and apply the division lemma to get

439 = 164 x 2 + 111

We consider the new divisor 164 and the new remainder 111,and apply the division lemma to get

164 = 111 x 1 + 53

We consider the new divisor 111 and the new remainder 53,and apply the division lemma to get

111 = 53 x 2 + 5

We consider the new divisor 53 and the new remainder 5,and apply the division lemma to get

53 = 5 x 10 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

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 603 and 7072 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(53,5) = HCF(111,53) = HCF(164,111) = HCF(439,164) = HCF(603,439) = HCF(7072,603) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 4431 > 1, we apply the division lemma to 4431 and 1, to get

4431 = 1 x 4431 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4431 is 1

Notice that 1 = HCF(4431,1) .
