HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 450, 286 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 450, 286 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 637, 450, 286 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 637, 450, 286 is 1.

HCF(637, 450, 286) = 1

HCF of 637, 450, 286 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 637, 450, 286 is 1.

Highest Common Factor of 637,450,286 using Euclid's algorithm

Highest Common Factor of 637,450,286 is 1

Step 1: Since 637 > 450, we apply the division lemma to 637 and 450, to get

637 = 450 x 1 + 187

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 187 and 450, to get

450 = 187 x 2 + 76

Step 3: We consider the new divisor 187 and the new remainder 76, and apply the division lemma to get

187 = 76 x 2 + 35

We consider the new divisor 76 and the new remainder 35,and apply the division lemma to get

76 = 35 x 2 + 6

We consider the new divisor 35 and the new remainder 6,and apply the division lemma to get

35 = 6 x 5 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 637 and 450 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(35,6) = HCF(76,35) = HCF(187,76) = HCF(450,187) = HCF(637,450) .

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

Step 1: Since 286 > 1, we apply the division lemma to 286 and 1, to get

286 = 1 x 286 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 286 is 1

Notice that 1 = HCF(286,1) .
