HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 258, 508 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 402, 258, 508 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 402, 258, 508 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 402, 258, 508 is 2.

HCF(402, 258, 508) = 2

Highest common factor (HCF) of 402, 258, 508 is 2.

Highest Common Factor of 402,258,508 using Euclid's algorithm

Highest Common Factor of 402,258,508 is 2

Step 1: Since 402 > 258, we apply the division lemma to 402 and 258, to get

402 = 258 x 1 + 144

Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 144 and 258, to get

258 = 144 x 1 + 114

Step 3: We consider the new divisor 144 and the new remainder 114, and apply the division lemma to get

144 = 114 x 1 + 30

We consider the new divisor 114 and the new remainder 30,and apply the division lemma to get

114 = 30 x 3 + 24

We consider the new divisor 30 and the new remainder 24,and apply the division lemma to get

30 = 24 x 1 + 6

We consider the new divisor 24 and the new remainder 6,and apply the division lemma to get

24 = 6 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 402 and 258 is 6

Notice that 6 = HCF(24,6) = HCF(30,24) = HCF(114,30) = HCF(144,114) = HCF(258,144) = HCF(402,258) .

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

Step 1: Since 508 > 6, we apply the division lemma to 508 and 6, to get

508 = 6 x 84 + 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 508 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(508,6) .
