HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 603, 982, 821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 603, 982, 821 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, 982, 821 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, 982, 821 is 1.

HCF(603, 982, 821) = 1

HCF of 603, 982, 821 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 603, 982, 821 is 1.

Highest Common Factor of 603,982,821 using Euclid's algorithm

Highest Common Factor of 603,982,821 is 1

Step 1: Since 982 > 603, we apply the division lemma to 982 and 603, to get

982 = 603 x 1 + 379

Step 2: Since the reminder 603 ≠ 0, we apply division lemma to 379 and 603, to get

603 = 379 x 1 + 224

Step 3: We consider the new divisor 379 and the new remainder 224, and apply the division lemma to get

379 = 224 x 1 + 155

We consider the new divisor 224 and the new remainder 155,and apply the division lemma to get

224 = 155 x 1 + 69

We consider the new divisor 155 and the new remainder 69,and apply the division lemma to get

155 = 69 x 2 + 17

We consider the new divisor 69 and the new remainder 17,and apply the division lemma to get

69 = 17 x 4 + 1

We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get

17 = 1 x 17 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 603 and 982 is 1

Notice that 1 = HCF(17,1) = HCF(69,17) = HCF(155,69) = HCF(224,155) = HCF(379,224) = HCF(603,379) = HCF(982,603) .


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

Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get

821 = 1 x 821 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1

Notice that 1 = HCF(821,1) .
