HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 430, 289 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 479, 430, 289 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 479, 430, 289 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 479, 430, 289 is 1.

HCF(479, 430, 289) = 1

Highest common factor (HCF) of 479, 430, 289 is 1.

Highest Common Factor of 479,430,289 using Euclid's algorithm

Highest Common Factor of 479,430,289 is 1

Step 1: Since 479 > 430, we apply the division lemma to 479 and 430, to get

479 = 430 x 1 + 49

Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 49 and 430, to get

430 = 49 x 8 + 38

Step 3: We consider the new divisor 49 and the new remainder 38, and apply the division lemma to get

49 = 38 x 1 + 11

We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get

38 = 11 x 3 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 430 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(49,38) = HCF(430,49) = HCF(479,430) .

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

Step 1: Since 289 > 1, we apply the division lemma to 289 and 1, to get

289 = 1 x 289 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 289 is 1

Notice that 1 = HCF(289,1) .
