HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 601, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 990, 601, 486 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 990, 601, 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 990, 601, 486 is 1.

HCF(990, 601, 486) = 1

HCF of 990, 601, 486 using Euclid's algorithm

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

Highest common factor (HCF) of 990, 601, 486 is 1.

Highest Common Factor of 990,601,486 using Euclid's algorithm

Highest Common Factor of 990,601,486 is 1

Step 1: Since 990 > 601, we apply the division lemma to 990 and 601, to get

990 = 601 x 1 + 389

Step 2: Since the reminder 601 ≠ 0, we apply division lemma to 389 and 601, to get

601 = 389 x 1 + 212

Step 3: We consider the new divisor 389 and the new remainder 212, and apply the division lemma to get

389 = 212 x 1 + 177

We consider the new divisor 212 and the new remainder 177,and apply the division lemma to get

212 = 177 x 1 + 35

We consider the new divisor 177 and the new remainder 35,and apply the division lemma to get

177 = 35 x 5 + 2

We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get

35 = 2 x 17 + 1

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 990 and 601 is 1

Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(177,35) = HCF(212,177) = HCF(389,212) = HCF(601,389) = HCF(990,601) .

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

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

486 = 1 x 486 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 486 is 1

Notice that 1 = HCF(486,1) .
