HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 326, 723, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 326, 723, 225 is 1 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 326, 723, 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 326, 723, 225 is 1.

HCF(326, 723, 225) = 1

Highest common factor (HCF) of 326, 723, 225 is 1.

Highest Common Factor of 326,723,225 using Euclid's algorithm

Highest Common Factor of 326,723,225 is 1

Step 1: Since 723 > 326, we apply the division lemma to 723 and 326, to get

723 = 326 x 2 + 71

Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 71 and 326, to get

326 = 71 x 4 + 42

Step 3: We consider the new divisor 71 and the new remainder 42, and apply the division lemma to get

71 = 42 x 1 + 29

We consider the new divisor 42 and the new remainder 29,and apply the division lemma to get

42 = 29 x 1 + 13

We consider the new divisor 29 and the new remainder 13,and apply the division lemma to get

29 = 13 x 2 + 3

We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get

13 = 3 x 4 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 326 and 723 is 1

Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(29,13) = HCF(42,29) = HCF(71,42) = HCF(326,71) = HCF(723,326) .

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

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

225 = 1 x 225 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1

Notice that 1 = HCF(225,1) .
