HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 594, 420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 511, 594, 420 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 511, 594, 420 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 511, 594, 420 is 1.

HCF(511, 594, 420) = 1

Highest common factor (HCF) of 511, 594, 420 is 1.

Highest Common Factor of 511,594,420 using Euclid's algorithm

Highest Common Factor of 511,594,420 is 1

Step 1: Since 594 > 511, we apply the division lemma to 594 and 511, to get

594 = 511 x 1 + 83

Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 83 and 511, to get

511 = 83 x 6 + 13

Step 3: We consider the new divisor 83 and the new remainder 13, and apply the division lemma to get

83 = 13 x 6 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 511 and 594 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(83,13) = HCF(511,83) = HCF(594,511) .

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

Step 1: Since 420 > 1, we apply the division lemma to 420 and 1, to get

420 = 1 x 420 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 420 is 1

Notice that 1 = HCF(420,1) .
