HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 999, 746 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 486, 999, 746 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 486, 999, 746 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, 999, 746 is 1.

HCF(486, 999, 746) = 1

HCF of 486, 999, 746 using Euclid's algorithm

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

Highest common factor (HCF) of 486, 999, 746 is 1.

Highest Common Factor of 486,999,746 using Euclid's algorithm

Highest Common Factor of 486,999,746 is 1

Step 1: Since 999 > 486, we apply the division lemma to 999 and 486, to get

999 = 486 x 2 + 27

Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 27 and 486, to get

486 = 27 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 486 and 999 is 27

Notice that 27 = HCF(486,27) = HCF(999,486) .

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

Step 1: Since 746 > 27, we apply the division lemma to 746 and 27, to get

746 = 27 x 27 + 17

Step 2: Since the reminder 27 ≠ 0, we apply division lemma to 17 and 27, to get

27 = 17 x 1 + 10

Step 3: We consider the new divisor 17 and the new remainder 10, and apply the division lemma to get

17 = 10 x 1 + 7

We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get

10 = 7 x 1 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 27 and 746 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(27,17) = HCF(746,27) .
