HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 424, 770, 314 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 424, 770, 314 is 2 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 424, 770, 314 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 424, 770, 314 is 2.

HCF(424, 770, 314) = 2

Highest common factor (HCF) of 424, 770, 314 is 2.

Highest Common Factor of 424,770,314 using Euclid's algorithm

Highest Common Factor of 424,770,314 is 2

Step 1: Since 770 > 424, we apply the division lemma to 770 and 424, to get

770 = 424 x 1 + 346

Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 346 and 424, to get

424 = 346 x 1 + 78

Step 3: We consider the new divisor 346 and the new remainder 78, and apply the division lemma to get

346 = 78 x 4 + 34

We consider the new divisor 78 and the new remainder 34,and apply the division lemma to get

78 = 34 x 2 + 10

We consider the new divisor 34 and the new remainder 10,and apply the division lemma to get

34 = 10 x 3 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 424 and 770 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(34,10) = HCF(78,34) = HCF(346,78) = HCF(424,346) = HCF(770,424) .

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

Step 1: Since 314 > 2, we apply the division lemma to 314 and 2, to get

314 = 2 x 157 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 314 is 2

Notice that 2 = HCF(314,2) .
