HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 691, 308 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 440, 691, 308 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 440, 691, 308 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 440, 691, 308 is 1.

HCF(440, 691, 308) = 1

HCF of 440, 691, 308 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 440, 691, 308 is 1.

Highest Common Factor of 440,691,308 using Euclid's algorithm

Highest Common Factor of 440,691,308 is 1

Step 1: Since 691 > 440, we apply the division lemma to 691 and 440, to get

691 = 440 x 1 + 251

Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 251 and 440, to get

440 = 251 x 1 + 189

Step 3: We consider the new divisor 251 and the new remainder 189, and apply the division lemma to get

251 = 189 x 1 + 62

We consider the new divisor 189 and the new remainder 62,and apply the division lemma to get

189 = 62 x 3 + 3

We consider the new divisor 62 and the new remainder 3,and apply the division lemma to get

62 = 3 x 20 + 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 440 and 691 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(62,3) = HCF(189,62) = HCF(251,189) = HCF(440,251) = HCF(691,440) .

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

Step 1: Since 308 > 1, we apply the division lemma to 308 and 1, to get

308 = 1 x 308 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 308 is 1

Notice that 1 = HCF(308,1) .
