HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 595, 725, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 595, 725, 686 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 595, 725, 686 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 595, 725, 686 is 1.

HCF(595, 725, 686) = 1

Highest common factor (HCF) of 595, 725, 686 is 1.

Highest Common Factor of 595,725,686 using Euclid's algorithm

Highest Common Factor of 595,725,686 is 1

Step 1: Since 725 > 595, we apply the division lemma to 725 and 595, to get

725 = 595 x 1 + 130

Step 2: Since the reminder 595 ≠ 0, we apply division lemma to 130 and 595, to get

595 = 130 x 4 + 75

Step 3: We consider the new divisor 130 and the new remainder 75, and apply the division lemma to get

130 = 75 x 1 + 55

We consider the new divisor 75 and the new remainder 55,and apply the division lemma to get

75 = 55 x 1 + 20

We consider the new divisor 55 and the new remainder 20,and apply the division lemma to get

55 = 20 x 2 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 595 and 725 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(55,20) = HCF(75,55) = HCF(130,75) = HCF(595,130) = HCF(725,595) .

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

Step 1: Since 686 > 5, we apply the division lemma to 686 and 5, to get

686 = 5 x 137 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 686 is 1

Notice that 1 = HCF(5,1) = HCF(686,5) .
