HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 450, 990 i.e. 90 the largest integer that leaves a remainder zero for all numbers.

HCF of 450, 990 is 90 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 450, 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 450, 990 is 90.

HCF(450, 990) = 90

HCF of 450, 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 450, 990 is 90.

Highest Common Factor of 450,990 using Euclid's algorithm

Highest Common Factor of 450,990 is 90

Step 1: Since 990 > 450, we apply the division lemma to 990 and 450, to get

990 = 450 x 2 + 90

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 90 and 450, to get

450 = 90 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 90, the HCF of 450 and 990 is 90

Notice that 90 = HCF(450,90) = HCF(990,450) .
