HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 393, 986, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 393, 986, 659 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 393, 986, 659 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 393, 986, 659 is 1.

HCF(393, 986, 659) = 1

HCF of 393, 986, 659 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 393, 986, 659 is 1.

Highest Common Factor of 393,986,659 using Euclid's algorithm

Highest Common Factor of 393,986,659 is 1

Step 1: Since 986 > 393, we apply the division lemma to 986 and 393, to get

986 = 393 x 2 + 200

Step 2: Since the reminder 393 ≠ 0, we apply division lemma to 200 and 393, to get

393 = 200 x 1 + 193

Step 3: We consider the new divisor 200 and the new remainder 193, and apply the division lemma to get

200 = 193 x 1 + 7

We consider the new divisor 193 and the new remainder 7,and apply the division lemma to get

193 = 7 x 27 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 393 and 986 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(193,7) = HCF(200,193) = HCF(393,200) = HCF(986,393) .

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

Step 1: Since 659 > 1, we apply the division lemma to 659 and 1, to get

659 = 1 x 659 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 659 is 1

Notice that 1 = HCF(659,1) .
