HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 719, 421, 246 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 719, 421, 246 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 719, 421, 246 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 719, 421, 246 is 1.

HCF(719, 421, 246) = 1

HCF of 719, 421, 246 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 719, 421, 246 is 1.

Highest Common Factor of 719,421,246 using Euclid's algorithm

Highest Common Factor of 719,421,246 is 1

Step 1: Since 719 > 421, we apply the division lemma to 719 and 421, to get

719 = 421 x 1 + 298

Step 2: Since the reminder 421 ≠ 0, we apply division lemma to 298 and 421, to get

421 = 298 x 1 + 123

Step 3: We consider the new divisor 298 and the new remainder 123, and apply the division lemma to get

298 = 123 x 2 + 52

We consider the new divisor 123 and the new remainder 52,and apply the division lemma to get

123 = 52 x 2 + 19

We consider the new divisor 52 and the new remainder 19,and apply the division lemma to get

52 = 19 x 2 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 719 and 421 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(52,19) = HCF(123,52) = HCF(298,123) = HCF(421,298) = HCF(719,421) .

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

Step 1: Since 246 > 1, we apply the division lemma to 246 and 1, to get

246 = 1 x 246 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 246 is 1

Notice that 1 = HCF(246,1) .
