HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 289, 488, 87 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 289, 488, 87 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 289, 488, 87 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 289, 488, 87 is 1.

HCF(289, 488, 87) = 1

Highest common factor (HCF) of 289, 488, 87 is 1.

Highest Common Factor of 289,488,87 using Euclid's algorithm

Highest Common Factor of 289,488,87 is 1

Step 1: Since 488 > 289, we apply the division lemma to 488 and 289, to get

488 = 289 x 1 + 199

Step 2: Since the reminder 289 ≠ 0, we apply division lemma to 199 and 289, to get

289 = 199 x 1 + 90

Step 3: We consider the new divisor 199 and the new remainder 90, and apply the division lemma to get

199 = 90 x 2 + 19

We consider the new divisor 90 and the new remainder 19,and apply the division lemma to get

90 = 19 x 4 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 289 and 488 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(90,19) = HCF(199,90) = HCF(289,199) = HCF(488,289) .

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

Step 1: Since 87 > 1, we apply the division lemma to 87 and 1, to get

87 = 1 x 87 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 87 is 1

Notice that 1 = HCF(87,1) .
