HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 815, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 195, 815, 712 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 195, 815, 712 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 195, 815, 712 is 1.

HCF(195, 815, 712) = 1

HCF of 195, 815, 712 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 195, 815, 712 is 1.

Highest Common Factor of 195,815,712 using Euclid's algorithm

Highest Common Factor of 195,815,712 is 1

Step 1: Since 815 > 195, we apply the division lemma to 815 and 195, to get

815 = 195 x 4 + 35

Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 35 and 195, to get

195 = 35 x 5 + 20

Step 3: We consider the new divisor 35 and the new remainder 20, and apply the division lemma to get

35 = 20 x 1 + 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 195 and 815 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(195,35) = HCF(815,195) .

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

Step 1: Since 712 > 5, we apply the division lemma to 712 and 5, to get

712 = 5 x 142 + 2

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

5 = 2 x 2 + 1

Step 3: 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 5 and 712 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(712,5) .
