HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 396, 725 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 724, 396, 725 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 724, 396, 725 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 724, 396, 725 is 1.

HCF(724, 396, 725) = 1

Highest Common Factor of 724,396,725 using Euclid's algorithm

Highest Common Factor of 724,396,725 is 1

Step 1: Since 724 > 396, we apply the division lemma to 724 and 396, to get

724 = 396 x 1 + 328

Step 2: Since the reminder 396 ≠ 0, we apply division lemma to 328 and 396, to get

396 = 328 x 1 + 68

Step 3: We consider the new divisor 328 and the new remainder 68, and apply the division lemma to get

328 = 68 x 4 + 56

We consider the new divisor 68 and the new remainder 56,and apply the division lemma to get

68 = 56 x 1 + 12

We consider the new divisor 56 and the new remainder 12,and apply the division lemma to get

56 = 12 x 4 + 8

We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get

12 = 8 x 1 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 724 and 396 is 4

Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(56,12) = HCF(68,56) = HCF(328,68) = HCF(396,328) = HCF(724,396) .

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

Step 1: Since 725 > 4, we apply the division lemma to 725 and 4, to get

725 = 4 x 181 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 725 is 1

Notice that 1 = HCF(4,1) = HCF(725,4) .
