HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 265, 725, 869 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 265, 725, 869 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 265, 725, 869 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 265, 725, 869 is 1.

HCF(265, 725, 869) = 1

Highest Common Factor of 265,725,869 using Euclid's algorithm

Highest Common Factor of 265,725,869 is 1

Step 1: Since 725 > 265, we apply the division lemma to 725 and 265, to get

725 = 265 x 2 + 195

Step 2: Since the reminder 265 ≠ 0, we apply division lemma to 195 and 265, to get

265 = 195 x 1 + 70

Step 3: We consider the new divisor 195 and the new remainder 70, and apply the division lemma to get

195 = 70 x 2 + 55

We consider the new divisor 70 and the new remainder 55,and apply the division lemma to get

70 = 55 x 1 + 15

We consider the new divisor 55 and the new remainder 15,and apply the division lemma to get

55 = 15 x 3 + 10

We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get

15 = 10 x 1 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 265 and 725 is 5

Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(55,15) = HCF(70,55) = HCF(195,70) = HCF(265,195) = HCF(725,265) .

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

Step 1: Since 869 > 5, we apply the division lemma to 869 and 5, to get

869 = 5 x 173 + 4

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get

5 = 4 x 1 + 1

Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma 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 5 and 869 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(869,5) .
