HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 268, 305 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 343, 268, 305 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 343, 268, 305 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 343, 268, 305 is 1.

HCF(343, 268, 305) = 1

Highest common factor (HCF) of 343, 268, 305 is 1.

Highest Common Factor of 343,268,305 using Euclid's algorithm

Highest Common Factor of 343,268,305 is 1

Step 1: Since 343 > 268, we apply the division lemma to 343 and 268, to get

343 = 268 x 1 + 75

Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 75 and 268, to get

268 = 75 x 3 + 43

Step 3: We consider the new divisor 75 and the new remainder 43, and apply the division lemma to get

75 = 43 x 1 + 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 343 and 268 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(75,43) = HCF(268,75) = HCF(343,268) .

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

Step 1: Since 305 > 1, we apply the division lemma to 305 and 1, to get

305 = 1 x 305 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 305 is 1

Notice that 1 = HCF(305,1) .
