HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 225, 663 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 225, 663 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 225, 663 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 225, 663 is 3.

HCF(225, 663) = 3

HCF of 225, 663 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 225, 663 is 3.

Highest Common Factor of 225,663 using Euclid's algorithm

Highest Common Factor of 225,663 is 3

Step 1: Since 663 > 225, we apply the division lemma to 663 and 225, to get

663 = 225 x 2 + 213

Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 213 and 225, to get

225 = 213 x 1 + 12

Step 3: We consider the new divisor 213 and the new remainder 12, and apply the division lemma to get

213 = 12 x 17 + 9

We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get

12 = 9 x 1 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 225 and 663 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(213,12) = HCF(225,213) = HCF(663,225) .
