HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 568, 138, 125 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 568, 138, 125 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 568, 138, 125 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 568, 138, 125 is 1.

HCF(568, 138, 125) = 1

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

HCF of:

Highest common factor (HCF) of 568, 138, 125 is 1.

Highest Common Factor of 568,138,125 using Euclid's algorithm

Highest Common Factor of 568,138,125 is 1

Step 1: Since 568 > 138, we apply the division lemma to 568 and 138, to get

568 = 138 x 4 + 16

Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 16 and 138, to get

138 = 16 x 8 + 10

Step 3: We consider the new divisor 16 and the new remainder 10, and apply the division lemma to get

16 = 10 x 1 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 568 and 138 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(138,16) = HCF(568,138) .

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

Step 1: Since 125 > 2, we apply the division lemma to 125 and 2, to get

125 = 2 x 62 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 125 is 1

Notice that 1 = HCF(2,1) = HCF(125,2) .
