HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 411, 990 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 411, 990 is 3 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 411, 990 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 411, 990 is 3.

HCF(411, 990) = 3

HCF of 411, 990 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 411, 990 is 3.

Highest Common Factor of 411,990 using Euclid's algorithm

Highest Common Factor of 411,990 is 3

Step 1: Since 990 > 411, we apply the division lemma to 990 and 411, to get

990 = 411 x 2 + 168

Step 2: Since the reminder 411 ≠ 0, we apply division lemma to 168 and 411, to get

411 = 168 x 2 + 75

Step 3: We consider the new divisor 168 and the new remainder 75, and apply the division lemma to get

168 = 75 x 2 + 18

We consider the new divisor 75 and the new remainder 18,and apply the division lemma to get

75 = 18 x 4 + 3

We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get

18 = 3 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 411 and 990 is 3

Notice that 3 = HCF(18,3) = HCF(75,18) = HCF(168,75) = HCF(411,168) = HCF(990,411) .
