HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 837 i.e. 27 the largest integer that leaves a remainder zero for all numbers.

HCF of 486, 837 is 27 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 486, 837 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 486, 837 is 27.

HCF(486, 837) = 27

HCF of 486, 837 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 486, 837 is 27.

Highest Common Factor of 486,837 using Euclid's algorithm

Highest Common Factor of 486,837 is 27

Step 1: Since 837 > 486, we apply the division lemma to 837 and 486, to get

837 = 486 x 1 + 351

Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 351 and 486, to get

486 = 351 x 1 + 135

Step 3: We consider the new divisor 351 and the new remainder 135, and apply the division lemma to get

351 = 135 x 2 + 81

We consider the new divisor 135 and the new remainder 81,and apply the division lemma to get

135 = 81 x 1 + 54

We consider the new divisor 81 and the new remainder 54,and apply the division lemma to get

81 = 54 x 1 + 27

We consider the new divisor 54 and the new remainder 27,and apply the division lemma to get

54 = 27 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 486 and 837 is 27

Notice that 27 = HCF(54,27) = HCF(81,54) = HCF(135,81) = HCF(351,135) = HCF(486,351) = HCF(837,486) .
