HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 238, 618, 363 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 238, 618, 363 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 238, 618, 363 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 238, 618, 363 is 1.

HCF(238, 618, 363) = 1

Highest common factor (HCF) of 238, 618, 363 is 1.

Highest Common Factor of 238,618,363 using Euclid's algorithm

Highest Common Factor of 238,618,363 is 1

Step 1: Since 618 > 238, we apply the division lemma to 618 and 238, to get

618 = 238 x 2 + 142

Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 142 and 238, to get

238 = 142 x 1 + 96

Step 3: We consider the new divisor 142 and the new remainder 96, and apply the division lemma to get

142 = 96 x 1 + 46

We consider the new divisor 96 and the new remainder 46,and apply the division lemma to get

96 = 46 x 2 + 4

We consider the new divisor 46 and the new remainder 4,and apply the division lemma to get

46 = 4 x 11 + 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 238 and 618 is 2

Notice that 2 = HCF(4,2) = HCF(46,4) = HCF(96,46) = HCF(142,96) = HCF(238,142) = HCF(618,238) .

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

Step 1: Since 363 > 2, we apply the division lemma to 363 and 2, to get

363 = 2 x 181 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 363 is 1

Notice that 1 = HCF(2,1) = HCF(363,2) .
