HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 630, 202 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 404, 630, 202 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 404, 630, 202 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 404, 630, 202 is 2.

HCF(404, 630, 202) = 2

Highest Common Factor of 404,630,202 using Euclid's algorithm

Highest Common Factor of 404,630,202 is 2

Step 1: Since 630 > 404, we apply the division lemma to 630 and 404, to get

630 = 404 x 1 + 226

Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 226 and 404, to get

404 = 226 x 1 + 178

Step 3: We consider the new divisor 226 and the new remainder 178, and apply the division lemma to get

226 = 178 x 1 + 48

We consider the new divisor 178 and the new remainder 48,and apply the division lemma to get

178 = 48 x 3 + 34

We consider the new divisor 48 and the new remainder 34,and apply the division lemma to get

48 = 34 x 1 + 14

We consider the new divisor 34 and the new remainder 14,and apply the division lemma to get

34 = 14 x 2 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 404 and 630 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(34,14) = HCF(48,34) = HCF(178,48) = HCF(226,178) = HCF(404,226) = HCF(630,404) .

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

Step 1: Since 202 > 2, we apply the division lemma to 202 and 2, to get

202 = 2 x 101 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 202 is 2

Notice that 2 = HCF(202,2) .
