HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 483, 609, 291 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 483, 609, 291 is 3 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 483, 609, 291 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 483, 609, 291 is 3.

HCF(483, 609, 291) = 3

HCF of 483, 609, 291 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 483, 609, 291 is 3.

Highest Common Factor of 483,609,291 using Euclid's algorithm

Highest Common Factor of 483,609,291 is 3

Step 1: Since 609 > 483, we apply the division lemma to 609 and 483, to get

609 = 483 x 1 + 126

Step 2: Since the reminder 483 ≠ 0, we apply division lemma to 126 and 483, to get

483 = 126 x 3 + 105

Step 3: We consider the new divisor 126 and the new remainder 105, and apply the division lemma to get

126 = 105 x 1 + 21

We consider the new divisor 105 and the new remainder 21, and apply the division lemma to get

105 = 21 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 483 and 609 is 21

Notice that 21 = HCF(105,21) = HCF(126,105) = HCF(483,126) = HCF(609,483) .


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

Step 1: Since 291 > 21, we apply the division lemma to 291 and 21, to get

291 = 21 x 13 + 18

Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 18 and 21, to get

21 = 18 x 1 + 3

Step 3: We consider the new divisor 18 and the new remainder 3, and apply the division lemma to get

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 21 and 291 is 3

Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(291,21) .
