HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 675, 450 i.e. 75 the largest integer that leaves a remainder zero for all numbers.

HCF of 825, 675, 450 is 75 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 825, 675, 450 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 825, 675, 450 is 75.

HCF(825, 675, 450) = 75

## HCF of 825, 675, 450 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 825, 675, 450 is 75. ### Highest Common Factor of 825,675,450 is 75

Step 1: Since 825 > 675, we apply the division lemma to 825 and 675, to get

825 = 675 x 1 + 150

Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 150 and 675, to get

675 = 150 x 4 + 75

Step 3: We consider the new divisor 150 and the new remainder 75, and apply the division lemma to get

150 = 75 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 75, the HCF of 825 and 675 is 75

Notice that 75 = HCF(150,75) = HCF(675,150) = HCF(825,675) .

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

Step 1: Since 450 > 75, we apply the division lemma to 450 and 75, to get

450 = 75 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 75, the HCF of 75 and 450 is 75

Notice that 75 = HCF(450,75) .
