HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 87, 486, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 87, 486, 437 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 87, 486, 437 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 87, 486, 437 is 1.

HCF(87, 486, 437) = 1

Highest common factor (HCF) of 87, 486, 437 is 1.

Highest Common Factor of 87,486,437 using Euclid's algorithm

Highest Common Factor of 87,486,437 is 1

Step 1: Since 486 > 87, we apply the division lemma to 486 and 87, to get

486 = 87 x 5 + 51

Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 51 and 87, to get

87 = 51 x 1 + 36

Step 3: We consider the new divisor 51 and the new remainder 36, and apply the division lemma to get

51 = 36 x 1 + 15

We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get

36 = 15 x 2 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 87 and 486 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(51,36) = HCF(87,51) = HCF(486,87) .

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

Step 1: Since 437 > 3, we apply the division lemma to 437 and 3, to get

437 = 3 x 145 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 437 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(437,3) .
