HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 486 i.e. 9 the largest integer that leaves a remainder zero for all numbers.

HCF of 477, 486 is 9 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 477, 486 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 477, 486 is 9.

HCF(477, 486) = 9

HCF of 477, 486 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 477, 486 is 9.

Highest Common Factor of 477,486 using Euclid's algorithm

Highest Common Factor of 477,486 is 9

Step 1: Since 486 > 477, we apply the division lemma to 486 and 477, to get

486 = 477 x 1 + 9

Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 9 and 477, to get

477 = 9 x 53 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 477 and 486 is 9

Notice that 9 = HCF(477,9) = HCF(486,477) .
