HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 196, 240 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 196, 240 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 855, 196, 240 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 855, 196, 240 is 1.

HCF(855, 196, 240) = 1

HCF of 855, 196, 240 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 855, 196, 240 is 1.

Highest Common Factor of 855,196,240 using Euclid's algorithm

Highest Common Factor of 855,196,240 is 1

Step 1: Since 855 > 196, we apply the division lemma to 855 and 196, to get

855 = 196 x 4 + 71

Step 2: Since the reminder 196 ≠ 0, we apply division lemma to 71 and 196, to get

196 = 71 x 2 + 54

Step 3: We consider the new divisor 71 and the new remainder 54, and apply the division lemma to get

71 = 54 x 1 + 17

We consider the new divisor 54 and the new remainder 17,and apply the division lemma to get

54 = 17 x 3 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 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 855 and 196 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(54,17) = HCF(71,54) = HCF(196,71) = HCF(855,196) .

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

Step 1: Since 240 > 1, we apply the division lemma to 240 and 1, to get

240 = 1 x 240 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 240 is 1

Notice that 1 = HCF(240,1) .
