HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 247, 698, 279 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 247, 698, 279 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 247, 698, 279 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 247, 698, 279 is 1.

HCF(247, 698, 279) = 1

Highest common factor (HCF) of 247, 698, 279 is 1.

Highest Common Factor of 247,698,279 using Euclid's algorithm

Highest Common Factor of 247,698,279 is 1

Step 1: Since 698 > 247, we apply the division lemma to 698 and 247, to get

698 = 247 x 2 + 204

Step 2: Since the reminder 247 ≠ 0, we apply division lemma to 204 and 247, to get

247 = 204 x 1 + 43

Step 3: We consider the new divisor 204 and the new remainder 43, and apply the division lemma to get

204 = 43 x 4 + 32

We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get

43 = 32 x 1 + 11

We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get

32 = 11 x 2 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 247 and 698 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(204,43) = HCF(247,204) = HCF(698,247) .

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

Step 1: Since 279 > 1, we apply the division lemma to 279 and 1, to get

279 = 1 x 279 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 279 is 1

Notice that 1 = HCF(279,1) .
