HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 294, 810, 225 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 294, 810, 225 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 294, 810, 225 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 294, 810, 225 is 3.

HCF(294, 810, 225) = 3

HCF of 294, 810, 225 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 294, 810, 225 is 3.

Highest Common Factor of 294,810,225 using Euclid's algorithm

Highest Common Factor of 294,810,225 is 3

Step 1: Since 810 > 294, we apply the division lemma to 810 and 294, to get

810 = 294 x 2 + 222

Step 2: Since the reminder 294 ≠ 0, we apply division lemma to 222 and 294, to get

294 = 222 x 1 + 72

Step 3: We consider the new divisor 222 and the new remainder 72, and apply the division lemma to get

222 = 72 x 3 + 6

We consider the new divisor 72 and the new remainder 6, and apply the division lemma to get

72 = 6 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 294 and 810 is 6

Notice that 6 = HCF(72,6) = HCF(222,72) = HCF(294,222) = HCF(810,294) .


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

Step 1: Since 225 > 6, we apply the division lemma to 225 and 6, to get

225 = 6 x 37 + 3

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 225 is 3

Notice that 3 = HCF(6,3) = HCF(225,6) .
