HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 125, 725, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 125, 725, 861 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 125, 725, 861 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 125, 725, 861 is 1.

HCF(125, 725, 861) = 1

Highest common factor (HCF) of 125, 725, 861 is 1.

Highest Common Factor of 125,725,861 using Euclid's algorithm

Highest Common Factor of 125,725,861 is 1

Step 1: Since 725 > 125, we apply the division lemma to 725 and 125, to get

725 = 125 x 5 + 100

Step 2: Since the reminder 125 ≠ 0, we apply division lemma to 100 and 125, to get

125 = 100 x 1 + 25

Step 3: We consider the new divisor 100 and the new remainder 25, and apply the division lemma to get

100 = 25 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 125 and 725 is 25

Notice that 25 = HCF(100,25) = HCF(125,100) = HCF(725,125) .

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

Step 1: Since 861 > 25, we apply the division lemma to 861 and 25, to get

861 = 25 x 34 + 11

Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 11 and 25, to get

25 = 11 x 2 + 3

Step 3: We consider the new divisor 11 and the new remainder 3, and apply the division lemma to get

11 = 3 x 3 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 25 and 861 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(861,25) .
