HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 482, 202, 538 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 482, 202, 538 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 482, 202, 538 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 482, 202, 538 is 2.

HCF(482, 202, 538) = 2

Highest Common Factor of 482,202,538 using Euclid's algorithm

Highest Common Factor of 482,202,538 is 2

Step 1: Since 482 > 202, we apply the division lemma to 482 and 202, to get

482 = 202 x 2 + 78

Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 78 and 202, to get

202 = 78 x 2 + 46

Step 3: We consider the new divisor 78 and the new remainder 46, and apply the division lemma to get

78 = 46 x 1 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

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 482 and 202 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(78,46) = HCF(202,78) = HCF(482,202) .

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

Step 1: Since 538 > 2, we apply the division lemma to 538 and 2, to get

538 = 2 x 269 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 538 is 2

Notice that 2 = HCF(538,2) .
