HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 794, 419, 218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 794, 419, 218 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 794, 419, 218 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 794, 419, 218 is 1.

HCF(794, 419, 218) = 1

HCF of 794, 419, 218 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 794, 419, 218 is 1.

Highest Common Factor of 794,419,218 using Euclid's algorithm

Highest Common Factor of 794,419,218 is 1

Step 1: Since 794 > 419, we apply the division lemma to 794 and 419, to get

794 = 419 x 1 + 375

Step 2: Since the reminder 419 ≠ 0, we apply division lemma to 375 and 419, to get

419 = 375 x 1 + 44

Step 3: We consider the new divisor 375 and the new remainder 44, and apply the division lemma to get

375 = 44 x 8 + 23

We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get

44 = 23 x 1 + 21

We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get

23 = 21 x 1 + 2

We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get

21 = 2 x 10 + 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 794 and 419 is 1

Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(375,44) = HCF(419,375) = HCF(794,419) .

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

Step 1: Since 218 > 1, we apply the division lemma to 218 and 1, to get

218 = 1 x 218 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 218 is 1

Notice that 1 = HCF(218,1) .
