HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 720, 287 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 419, 720, 287 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 419, 720, 287 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 419, 720, 287 is 1.

HCF(419, 720, 287) = 1

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

HCF of:

Highest common factor (HCF) of 419, 720, 287 is 1.

Highest Common Factor of 419,720,287 using Euclid's algorithm

Highest Common Factor of 419,720,287 is 1

Step 1: Since 720 > 419, we apply the division lemma to 720 and 419, to get

720 = 419 x 1 + 301

Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 301 and 419, to get

419 = 301 x 1 + 118

Step 3: We consider the new divisor 301 and the new remainder 118, and apply the division lemma to get

301 = 118 x 2 + 65

We consider the new divisor 118 and the new remainder 65,and apply the division lemma to get

118 = 65 x 1 + 53

We consider the new divisor 65 and the new remainder 53,and apply the division lemma to get

65 = 53 x 1 + 12

We consider the new divisor 53 and the new remainder 12,and apply the division lemma to get

53 = 12 x 4 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 419 and 720 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(53,12) = HCF(65,53) = HCF(118,65) = HCF(301,118) = HCF(419,301) = HCF(720,419) .


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

Step 1: Since 287 > 1, we apply the division lemma to 287 and 1, to get

287 = 1 x 287 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 287 is 1

Notice that 1 = HCF(287,1) .
