HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 680, 386 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 507, 680, 386 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 507, 680, 386 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 507, 680, 386 is 1.

HCF(507, 680, 386) = 1

Highest common factor (HCF) of 507, 680, 386 is 1.

Highest Common Factor of 507,680,386 using Euclid's algorithm

Highest Common Factor of 507,680,386 is 1

Step 1: Since 680 > 507, we apply the division lemma to 680 and 507, to get

680 = 507 x 1 + 173

Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 173 and 507, to get

507 = 173 x 2 + 161

Step 3: We consider the new divisor 173 and the new remainder 161, and apply the division lemma to get

173 = 161 x 1 + 12

We consider the new divisor 161 and the new remainder 12,and apply the division lemma to get

161 = 12 x 13 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 507 and 680 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(161,12) = HCF(173,161) = HCF(507,173) = HCF(680,507) .

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

Step 1: Since 386 > 1, we apply the division lemma to 386 and 1, to get

386 = 1 x 386 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 386 is 1

Notice that 1 = HCF(386,1) .
