HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 918, 833, 203 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 630, 918, 833, 203 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 630, 918, 833, 203 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 630, 918, 833, 203 is 1.

HCF(630, 918, 833, 203) = 1

Highest common factor (HCF) of 630, 918, 833, 203 is 1.

Highest Common Factor of 630,918,833,203 using Euclid's algorithm

Highest Common Factor of 630,918,833,203 is 1

Step 1: Since 918 > 630, we apply the division lemma to 918 and 630, to get

918 = 630 x 1 + 288

Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 288 and 630, to get

630 = 288 x 2 + 54

Step 3: We consider the new divisor 288 and the new remainder 54, and apply the division lemma to get

288 = 54 x 5 + 18

We consider the new divisor 54 and the new remainder 18, and apply the division lemma to get

54 = 18 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 630 and 918 is 18

Notice that 18 = HCF(54,18) = HCF(288,54) = HCF(630,288) = HCF(918,630) .

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

Step 1: Since 833 > 18, we apply the division lemma to 833 and 18, to get

833 = 18 x 46 + 5

Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 5 and 18, to get

18 = 5 x 3 + 3

Step 3: We consider the new divisor 5 and the new remainder 3, and apply the division lemma to get

5 = 3 x 1 + 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 18 and 833 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(833,18) .

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

Step 1: Since 203 > 1, we apply the division lemma to 203 and 1, to get

203 = 1 x 203 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 203 is 1

Notice that 1 = HCF(203,1) .
