HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 630, 808, 308 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 804, 630, 808, 308 is 2 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 804, 630, 808, 308 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 804, 630, 808, 308 is 2.

HCF(804, 630, 808, 308) = 2

Highest common factor (HCF) of 804, 630, 808, 308 is 2.

Highest Common Factor of 804,630,808,308 using Euclid's algorithm

Highest Common Factor of 804,630,808,308 is 2

Step 1: Since 804 > 630, we apply the division lemma to 804 and 630, to get

804 = 630 x 1 + 174

Step 2: Since the reminder 630 ≠ 0, we apply division lemma to 174 and 630, to get

630 = 174 x 3 + 108

Step 3: We consider the new divisor 174 and the new remainder 108, and apply the division lemma to get

174 = 108 x 1 + 66

We consider the new divisor 108 and the new remainder 66,and apply the division lemma to get

108 = 66 x 1 + 42

We consider the new divisor 66 and the new remainder 42,and apply the division lemma to get

66 = 42 x 1 + 24

We consider the new divisor 42 and the new remainder 24,and apply the division lemma to get

42 = 24 x 1 + 18

We consider the new divisor 24 and the new remainder 18,and apply the division lemma to get

24 = 18 x 1 + 6

We consider the new divisor 18 and the new remainder 6,and apply the division lemma to get

18 = 6 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 804 and 630 is 6

Notice that 6 = HCF(18,6) = HCF(24,18) = HCF(42,24) = HCF(66,42) = HCF(108,66) = HCF(174,108) = HCF(630,174) = HCF(804,630) .


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

Step 1: Since 808 > 6, we apply the division lemma to 808 and 6, to get

808 = 6 x 134 + 4

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 4 and 6, to get

6 = 4 x 1 + 2

Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 808 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(808,6) .


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

Step 1: Since 308 > 2, we apply the division lemma to 308 and 2, to get

308 = 2 x 154 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 308 is 2

Notice that 2 = HCF(308,2) .
