HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 794, 479, 784 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 794, 479, 784 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, 479, 784 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, 479, 784 is 1.

HCF(794, 479, 784) = 1

Highest common factor (HCF) of 794, 479, 784 is 1.

Highest Common Factor of 794,479,784 using Euclid's algorithm

Highest Common Factor of 794,479,784 is 1

Step 1: Since 794 > 479, we apply the division lemma to 794 and 479, to get

794 = 479 x 1 + 315

Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 315 and 479, to get

479 = 315 x 1 + 164

Step 3: We consider the new divisor 315 and the new remainder 164, and apply the division lemma to get

315 = 164 x 1 + 151

We consider the new divisor 164 and the new remainder 151,and apply the division lemma to get

164 = 151 x 1 + 13

We consider the new divisor 151 and the new remainder 13,and apply the division lemma to get

151 = 13 x 11 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 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 794 and 479 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(151,13) = HCF(164,151) = HCF(315,164) = HCF(479,315) = HCF(794,479) .

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

Step 1: Since 784 > 1, we apply the division lemma to 784 and 1, to get

784 = 1 x 784 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 784 is 1

Notice that 1 = HCF(784,1) .
