HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 933, 451 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 686, 933, 451 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 686, 933, 451 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 686, 933, 451 is 1.

HCF(686, 933, 451) = 1

HCF of 686, 933, 451 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 686, 933, 451 is 1.

Highest Common Factor of 686,933,451 using Euclid's algorithm

Highest Common Factor of 686,933,451 is 1

Step 1: Since 933 > 686, we apply the division lemma to 933 and 686, to get

933 = 686 x 1 + 247

Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 247 and 686, to get

686 = 247 x 2 + 192

Step 3: We consider the new divisor 247 and the new remainder 192, and apply the division lemma to get

247 = 192 x 1 + 55

We consider the new divisor 192 and the new remainder 55,and apply the division lemma to get

192 = 55 x 3 + 27

We consider the new divisor 55 and the new remainder 27,and apply the division lemma to get

55 = 27 x 2 + 1

We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get

27 = 1 x 27 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 686 and 933 is 1

Notice that 1 = HCF(27,1) = HCF(55,27) = HCF(192,55) = HCF(247,192) = HCF(686,247) = HCF(933,686) .

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

Step 1: Since 451 > 1, we apply the division lemma to 451 and 1, to get

451 = 1 x 451 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 451 is 1

Notice that 1 = HCF(451,1) .
