HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 272, 306 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 494, 272, 306 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 494, 272, 306 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 494, 272, 306 is 2.

HCF(494, 272, 306) = 2

Highest common factor (HCF) of 494, 272, 306 is 2.

Highest Common Factor of 494,272,306 using Euclid's algorithm

Highest Common Factor of 494,272,306 is 2

Step 1: Since 494 > 272, we apply the division lemma to 494 and 272, to get

494 = 272 x 1 + 222

Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 222 and 272, to get

272 = 222 x 1 + 50

Step 3: We consider the new divisor 222 and the new remainder 50, and apply the division lemma to get

222 = 50 x 4 + 22

We consider the new divisor 50 and the new remainder 22,and apply the division lemma to get

50 = 22 x 2 + 6

We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get

22 = 6 x 3 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 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 494 and 272 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(50,22) = HCF(222,50) = HCF(272,222) = HCF(494,272) .

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

Step 1: Since 306 > 2, we apply the division lemma to 306 and 2, to get

306 = 2 x 153 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 306 is 2

Notice that 2 = HCF(306,2) .
