HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 990, 605 i.e. 11 the largest integer that leaves a remainder zero for all numbers.

HCF of 462, 990, 605 is 11 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 462, 990, 605 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 462, 990, 605 is 11.

HCF(462, 990, 605) = 11

HCF of 462, 990, 605 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 462, 990, 605 is 11.

Highest Common Factor of 462,990,605 using Euclid's algorithm

Highest Common Factor of 462,990,605 is 11

Step 1: Since 990 > 462, we apply the division lemma to 990 and 462, to get

990 = 462 x 2 + 66

Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 66 and 462, to get

462 = 66 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 66, the HCF of 462 and 990 is 66

Notice that 66 = HCF(462,66) = HCF(990,462) .


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

Step 1: Since 605 > 66, we apply the division lemma to 605 and 66, to get

605 = 66 x 9 + 11

Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 11 and 66, to get

66 = 11 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 66 and 605 is 11

Notice that 11 = HCF(66,11) = HCF(605,66) .
