HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 484, 309 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 484, 309 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 484, 309 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 484, 309 is 1.

HCF(484, 309) = 1

Highest common factor (HCF) of 484, 309 is 1.

Highest Common Factor of 484,309 using Euclid's algorithm

Highest Common Factor of 484,309 is 1

Step 1: Since 484 > 309, we apply the division lemma to 484 and 309, to get

484 = 309 x 1 + 175

Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 175 and 309, to get

309 = 175 x 1 + 134

Step 3: We consider the new divisor 175 and the new remainder 134, and apply the division lemma to get

175 = 134 x 1 + 41

We consider the new divisor 134 and the new remainder 41,and apply the division lemma to get

134 = 41 x 3 + 11

We consider the new divisor 41 and the new remainder 11,and apply the division lemma to get

41 = 11 x 3 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 484 and 309 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(41,11) = HCF(134,41) = HCF(175,134) = HCF(309,175) = HCF(484,309) .
