HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 454, 238, 489 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 454, 238, 489 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 454, 238, 489 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 454, 238, 489 is 1.

HCF(454, 238, 489) = 1

Highest common factor (HCF) of 454, 238, 489 is 1.

Highest Common Factor of 454,238,489 using Euclid's algorithm

Highest Common Factor of 454,238,489 is 1

Step 1: Since 454 > 238, we apply the division lemma to 454 and 238, to get

454 = 238 x 1 + 216

Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 216 and 238, to get

238 = 216 x 1 + 22

Step 3: We consider the new divisor 216 and the new remainder 22, and apply the division lemma to get

216 = 22 x 9 + 18

We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get

22 = 18 x 1 + 4

We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get

18 = 4 x 4 + 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 454 and 238 is 2

Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(216,22) = HCF(238,216) = HCF(454,238) .

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

Step 1: Since 489 > 2, we apply the division lemma to 489 and 2, to get

489 = 2 x 244 + 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 489 is 1

Notice that 1 = HCF(2,1) = HCF(489,2) .
