HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 408, 169, 725 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 408, 169, 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 408, 169, 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 408, 169, 725 is 1.

HCF(408, 169, 725) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 408, 169, 725 is 1.

Highest Common Factor of 408,169,725 using Euclid's algorithm

Highest Common Factor of 408,169,725 is 1

Step 1: Since 408 > 169, we apply the division lemma to 408 and 169, to get

408 = 169 x 2 + 70

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 70 and 169, to get

169 = 70 x 2 + 29

Step 3: We consider the new divisor 70 and the new remainder 29, and apply the division lemma to get

70 = 29 x 2 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 408 and 169 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(169,70) = HCF(408,169) .

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

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

725 = 1 x 725 + 0

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

Notice that 1 = HCF(725,1) .
